Give it a try. Try to send CTRL-C and look if "sleep 10" (which is a subprocess) process terminates. ay...@aycan:~/haskell$ time ./deniz2 && ps -ef | grep sleep ^C real 0m0.707s user 0m0.001s sys 0m0.004s aycan 13098 4430 0 13:50:23 pts/7 0:00 grep sleep It terminates with ghc 6.10.3 on OpenSolaris.
