[Haskell-cafe] Race conditions with threadWait(Read/Write) and closeFdWith

[Leon Smith]

Right,  I'm not suggesting changing the allocation strategy.  (although, I
think that would be a simpler and more elegant solution...)     I'm
pointing out a problem and seeing if anybody has any insight into it,
without patching any kernels.  ;-)

best,
Leon
