[mod_python] Any support for on-time Initialization?

Jalil,

The best way to setup database connections is just to wait for the first 
request to come in.  Keep your database connection in a module name space 
that all of your pages share and it'll persist between connections so long 
as you don't explicitly close it.  Once you import a module it stays in the 
interpreter name space between requests so future requests have access to 
the module without having to load it again.

If you're interested in keeping "pools" of database connections then you 
may be considering one of the multi-threaded MPM's for Apache 2.  You'll 
save yourself a lot of hair pulling if you stick with the prefork mpm.  It 
bears saying that in the prefork mpm, each process does not share 
interpreter resources with the other processes.  This means each process 
will have it's own "pool" of database connections which may not bode well 
with your database server if you run a moderately heavy Apache load.
