probably comes from the fact that killing children is necessary but not enough.
You need to explicitly wait for their termination (try "man 2 wait").

Subject: Re: [gnugo-devel] GTP sometimes fails
It is failing on set_random_seed, which is the first command after getting the connection. Specifically it fails on my 3rd unit test -
It worked (tested by doing my 3 tests 100 times) by adding a usleep(1); after my fwrite() command and before doing the fgets() call.
I also now explicitly kill the child pid when I disconnect, but as far as I can tell that made no difference: ps still shows 300 [gnugo <defunct>] zombies, but they all disappear when my program closes.
I guess my usleep() is a kludge and the real problem is how I connect or disconnect. But as multiple connect/disconnects is probably only going to happen in my unit tests it is good enough.
