Hello,
Great!
I believe too I can save a syscall with returning value from waitpid instead of kill 0 trial.
Special thanks for show that I can use select instead of usleep(). Is it about any advantages, besides few typing and probably that Time::HiRes is not yet included in Perl-5.8 distribution?
I think I'd better use some specialized CPAN Test::* module for just to build FCGI::Spawn tests... ;-)
