Urm... so like if FreeBSD's getpid was 100x slower than Linux's then 
what exactly would it be?

If FreeBSD's implementation is needlessly precise (and hence slow) for 
Python, then our platform should have a workaround "fast version" that 
Linux has.  The "fast" version doesn't have to be the default (although 
linux's massive marketshare would prove otherwise) however our port 
should be patched to use the fast version.
