[Pythonmac-SIG] CXX/Numeric problem on MacOSX (was building vpython on MacOSX)

[Steve Spicklemire]

Hi Folks,

OK.. I think I'm narrowing this down... is it possible for one thread to 
have a problem.. thereby setting errno.. then another thread *checks* 
errno and assumes it's a problem with something it's done, where it was 
really another thread entirely?

thanks,
-steve
