Which works perfectly, thank you very much.

And it says that much in the manual, duh.  It's just that I was using
Spanish-translated dev manpages, which are, now I know, ahem, a bit
outdated.  E.g., sigaction(2) says that SA_RESETHAND is the default
behaviour of signal()...

Oh, well.  Firing up a mail to the translators.

Thanks again.
