Ah, a second look showed that I had misread the problem about portability of
WNOHANG. I thought I had read that not all platforms support WNOHANG. What it
actually said was:
Most systems support a non-blocking waitpid. Use Perl's standard Config.pm
module to find out:
use Config;
$has_nonblocking = $Config{d_waitpid} eq "define" ||
$Config{d_wait4} eq "define";
So it is waitpid itself that is not completely portable, and since we use it
(as well as WNOHANG) I won't worry about using it here.
> 5 secs is pretty short under extremely heavy load.... but 30 would be plenty
Yes, I was surprised to discover that it takes 4 seconds on my Macbook with
nothing loadinng it down. And 30 is too long to simply sleep without using
SIGUSR1. I'll code up a patch now.
