Description
Some build systems (at least strace and glib) seem to decide number of concurrent jobs based on a glibc-specific getconf(1) variable, _NPROCESSORS_ONLN.
It would be useful if we could emulate this. I don't think it is so hard to determine the number of current CPUs from C in Linux. Let's investigate.
