Comment:

 Partial fix:

 {{{

   * make hWaitForInput/hReady not fail with "invalid argument" on Windows
 }}}

 Unfortunately `inputReady()` now returns False for file handles on
 Windows, and hence neither `hReady` nor `hWaitForInput` work properly for
 file handles on Windows.  I'm changing the bug to reflect that.
