Sorry yes, via a system call. I had thought of
fopen("/proc/cpuinfo") | !strcmp("processor", blah) | wc
but i was looking for something more Posix/gnu-centric
like getnumprocessors()

It shows a listen socket on *:2270 , same as when the program is running.
I've never seen an orphan listen clean itself up in 10 years of *NIXing.
It did occur to me that i've also never seen Apache say something like:
"Failed to bind to port 80, EADDRINUSE". So i did a kill -9 on
apache and was surprised that there is no orphan listen on port 80.
Obviously, i'm doing something wrong. I guess i need to study the
apache source some more.
