is_mp(), sysconf, and atoi. (Statically-linked multithreaded app s broken on X86?)

Hans,

I don't pretend to even have a clue as to what you're talking about, but I was
wondering what you thought of the following idiom instead of what you had
in linux-threads.c. Am I being too anal?

If you're too busy to waste time on this, I understand.
