NIO::Selector
  allows reregistration of the same IO object across select calls
  closes
  allows deregistering closed IO objects
  knows which IO objects are registered
  deregisters IO objects
  reports if it is empty
  #initialize
    raises TypeError if given a non-Symbol parameter
    allows explicitly specifying a backend
      Supported backends: [:epoll, :poll, :select]
    raises ArgumentError if given an invalid backend
  select
    raises IOError if asked to select on a closed selector
    selects IO objects

    does not block on super small precision intervals
    iterates across selected objects with a block
  .backends
    knows all supported backends
  register
    registers IO objects
    raises when asked to register after closing
    raises TypeError if asked to register non-IO objects
  backend
    knows its backend
      Current backend: epoll
  timeouts
    raises ArgumentError if given a negative timeout
    waits for a timeout when selecting with reader
    waits for timeout when selecting from empty selector
  wakeup
    wakes up if signaled to from another thread
    raises IOError if asked to wake up a closed selector
NIO::ByteBuffer
  #capacity
    has the requested capacity
  #flip
    sets remaining to the previous position
    flips the bytebuffer
    sets limit to the previous position
  #inspect
    inspects the buffer offsets
  #rewind
    rewinds the buffer leaving the limit intact
  #remaining
    calculates the number of bytes remaining
  #full?
    returns false when there is space remaining in the buffer
    returns true when the buffer is full
  #mark
    returns self
  #position
    defaults to zero
  #initialize
    raises TypeError if given a bogus argument
  #get
    reads zeroes from a newly initialized buffer
    reads all remaining data if no length is given
    advances position as data is read
    raises NIO::ByteBuffer::UnderflowError if there is not enough data in the buffer
  #<<
    adds strings to the buffer
    raises TypeError if given a non-String type
    raises NIO::ByteBuffer::OverflowError if the buffer is full
  #each
    iterates over data in the buffer
  #limit=
    raises ArgumentError if specified limit is less than zero
    sets position to the new limit if the previous position is beyond the limit
