RE: I thought concurrent haskell was _preemptive_!

[George Russell]

I would like to add my strong support, as the person in charge of
transferring the UniForM workbench, for the implementation of
wait functions on input and output handles and input on Posix.FD 
which don't block everything else to be done urgently.  I think 
I suggested this in May, and was told it was coming soon
but it still hasn't appeared.  Otherwise it is possible that the
entire UniForM project may be held up for lack of this simple
facility.
