[mod_python] persistent, reliable globals

Hi,

I would like to set a global variable (in memory) from a module. I would 
then like to access this same global variable susequently by other 
modules at any other time, and have the value that was set there to be 
there (until, of course, Apache is restarted).

I have tried several ways of doing this, and it doesn't seem to be 
reliable - i.e., sometimes the global variable is set when I look at it, 
and sometimes it is still at its original state.

What am I doing wrong (or right)?

Thanks!
