hGetBufSome blocks when all available input is buffered (on Windows only)
See the attached program. On Windows, it blocks on hGetSome.
If I take out the hGetLine and hWaitForInput, hGetSome does not block. If I add <code>hSetBuffering h NoBuffering</code>, hGetBufSome still blocks after hWaitForInput because it does some buffering when it calls hLookAhead_.
