[mod_python] sys.path shared?

Sorry, I should have given this a bit more thought. If you're using a forked
process environment then I would expect the sys.path variables to be
separate for each request. If you're using a threaded mpm (which is what I
use) then I assume sys.path would work like global variables which are
shared across requests.

Can anyone put me right on my understanding of the way mod_python works in
an apache forked process environment.  Each process has its own embedded
interpreter and therefore its own sys.path variable. 

How is it possible for an apache instance/process with its own embedded
interpreter to 'reach' across and use/inherit another processes/interpreters
sys.path?
