I cannot reproduce the error myself anymore! I have no idea
what has changed; suddenly 'test1' and 'test2' both work
reliably -- whether I catch sigCHLD or not. It used to work
only when I did catch the signal. This is really bizarre.

The moment I see some strange behavior from these functions
again, I'll strace it right away and will come back to the
topic. Let's hope it never happens.

Thanks for the support everybody!
