Version 0.3.0.1:  (2015-11-20)
  * `getEventNonBlocking` and `peekEventNonBlocking` now raise an
    `IOException` when they are called on an inotify descriptor that
    has been closed and have an empty buffer,  instead of returning
    `Nothing`.  This is more in line with the behavior of other IO
    functions such as `Data.ByteString.hGetNonBlocking`.

  * Attempted to improve documentation.

Version 0.3.0.0:  (2015-11-20)
  * Use-after-close now result in exceptions rather than undefined behavior.

  * All functions are now (intended to be) thread-safe.

  * Masked async exceptions during a buffer fill,  which could otherwise
    have resulted in losing an entire buffer of events.   In particularly
    unlucky cases, it might have been possible that futher use of the buffer
    could have resulted in memory faults.

  * Masked async exceptions when closing a descriptor,  which could otherwise
    have resulted in leaking an inotify file descriptor.
