I didn't try ghc-5.02 since I haven't installed it yet.
Could you do that? The IO library in 5.00.2 had a bug in fdToHandle
which meant that it didn't put the file descriptor into non-blocking
mode, and I suspect this is the cause of your problem.
It works. Thank you.
Max.
Playing with GHC, I met some oddity.
Consider the example:
import IO
import Concurrent
import Posix
import PosixIO
main = do
(fdIn, fdIn_send) - createPipe
hIn_send - fdToHandle fdIn_send
hIn - fdToHandle fdIn
-- The waiter is a simple tk/tcl script

I tried this here on Linux/x86 with 5.02 and it seems to work fine.
Instead of the tcl/tk script you mentioned I used a FIFO in /tmp/fifo
and made the runProcess just call cat /tmp/fifo.
Which GHC version and platform is this on?
I forgot to say: that's ghc-5.00.1, linux.
