Well, that's nice to hear; still not as good as other Unixes, but if
you bothered to tell us where this patch could be found, then maybe
someone could use it. I looked at the Squid pages and the link for
"linux binaries and patches" isn't pingable.

That isn't "writing the code correctly", that's a blecherous
workaround when it's much cleaner to fix libc and/or the kernel to
allow a reasonable number of fd's per process.

It would be much better for you to fix or write code than throw around
childish insults at the authors of free programs.
