IO.pipe
  behaves like an NIO selectable

    selects readable objects
    does not select unwritable objects
  behaves like an NIO selectable stream

NIO::ByteBuffer
  #position
    defaults to zero
  #[]
    raises ArgumentError if the index is less than zero
    raises ArgumentError if the index exceeds the limit
    obtains bytes at a given index without altering position
  #flip
    sets remaining to the previous position
    sets limit to the previous position
    flips the bytebuffer
  I/O
    #write_to
      writes data from the buffer
      raises NIO::ByteBuffer::UnderflowError if the buffer is out of data
    #read_from
      reads data into the buffer
      raises NIO::ByteBuffer::OverflowError if the buffer is already full
      returns 0 if no data is available
  #rewind
    rewinds the buffer leaving the limit intact
  #initialize
    raises TypeError if given a bogus argument
  #each
    iterates over data in the buffer
  #<<
    raises NIO::ByteBuffer::OverflowError if the buffer is full
    raises TypeError if given a non-String type
    adds strings to the buffer
  #full?
    returns true when the buffer is full
    returns false when there is space remaining in the buffer
  #get
    raises NIO::ByteBuffer::UnderflowError if there is not enough data in the buffer
    reads zeroes from a newly initialized buffer
    advances position as data is read
    reads all remaining data if no length is given
  #capacity
    has the requested capacity
  #clear
    clears the buffer
  #mark
    returns self
  #remaining
    calculates the number of bytes remaining
  #reset
    returns to a previously marked position
    raises NIO::ByteBuffer::MarkUnsetError unless mark has been set
  #compact
    copies data from the current position to the beginning of the buffer
  #inspect
    inspects the buffer offsets
  #position=
    sets the buffer's position to a valid value
    raises ArgumentError if the specified position exceeds the limit
    raises ArgumentError if the specified position is less than zero
  #limit=
    preserves position and mark if they're less than the new limit
    clears the mark if the new limit is before the current mark
    raises ArgumentError if specified limit exceeds capacity
    sets the buffer's limit to a valid value
    raises ArgumentError if specified limit is less than zero
    sets position to the new limit if the previous position is beyond the limit
  #limit
    defaults to the buffer's capacity
TCPSocket
  behaves like an NIO selectable
    selects writable objects
    does not select unreadable objects
    selects readable objects
    does not select unwritable objects
  behaves like an NIO selectable stream

  connect
    selects writable when connected
  behaves like an NIO bidirectional stream
    keeps readiness after the selectable has been closed
    selects readable and writable
NIO acceptables
  TCPServer
    behaves like an NIO acceptable
      selects for read readiness
UDPSocket
  behaves like an NIO selectable
    selects writable objects
    selects readable objects
    does not select unreadable objects
    does not select unwritable objects (PENDING: come up with a UDPSocket that's blocked on writing)
OpenSSL::SSL::SSLSocket
  using TLS 1.3
    behaves like an NIO selectable stream
      selects readable when the other end closes
    behaves like an NIO selectable
      does not select unreadable objects

      selects readable objects
      does not select unwritable objects
      does not select unreadable objects
    behaves like an NIO selectable stream
      selects readable when the other end closes
NIO::Selector
  closes
  deregisters IO objects
  reports if it is empty
  knows which IO objects are registered
  allows deregistering closed IO objects
