This is something we changed in GHC 6.10.1, incedentally. Now SIGPIPE
doesn't silently exit the program, and it will get an exception instead.

Dear all,
I have a Haskell program (compiled with -threaded)
that calls an external executable via System.Process.runInteractiveCommand
(and then I do waitForProcess).
The external program finishes with exit_group ()
(I don't have source, but I see it from strace).
Then, my Haskell program dies
Solved - exit_group() wasn't the problem.
My wrapper program silently died from SIGPIPE.
Best regards, J.W.
