I think we also do agree on the potential side issues related to portability :)

Yes.

I was thinking about a signal problem that a guy had about 6 months ago related to Apple OS X. We were using C and not Perl.

Your one line of code will work at least 99% of the time!
My 2 lines of code may work at a higher probability, but I don't think that it matters at all!

The "right way" to deal with this is to have a CHLD signal handler. And either set that thing to "IGNORE' or a coderef to a subroutine that causes a waitpid loop. $SIG{CHLD}='IGNORE'; is far superior to doing nothing with the CHLD signal.
