Sorry for the crud, then, just trying to find anything that might cause 
problems.

Already had:

...and unless they don't contain ".core" in their name, there are no

I've already seen this issue, and it's apparently not the cause here. 
According to the guy who installed it, Python was compiled with the 
"HUGE_STACK_SIZE" option, which was the root of those problems. Good 
thought, though. :-)
