-----------------------------------------+----------------------------------
The documentation for System.IO.hWaitForInput states that "in the current
 implementation, (...) if t is non-zero, then all other concurrent threads
 are blocked until data is available"

 This is not true in GHC 6.6 on Windows. Both threads forked with forkIO
 and forkOS continue working normally.

 Most likely an oversight. Might be in more places.
