see above
The processes are forked and don't share the perl iterpreter, that's why
it's impossible to do what you are trying to do.
If you try to reload data it's doable by many ways (IPC, dbm, etc), not
the code.
Currently Apache::Reload or its equivalent your only solution. With
mod_perl 2.0 it'll be doable, if you run a single threaded server.
