I recently ran out of processes on my system (64-bit Fedora 18) while running "make test". Quick inspection showed a vast number of defunct "tee" processes"

$ps ax

driver.pl uses tee to allow it to both capture and display the output. However it seems that when the child test completes, the tee process is not killed (problem with SIGCHILD?). I'd appreciate any suggestions of how to fix this - beyond the obvious one of using ulimit -u to increase the number of processes.

Fixed it to not use tee at all.

Fixed in git towards 3.848.
