You don't need to do this. Variables are not shared between perl
threads unless you make them shared. If you avo
I tried the cleanup handler solution, and threw a sleep in there for ha

Register a cleanup on the request's pool
Check if I need to do something to the user agent if it is found in an array

If it's not in the array, de
This module is meant for other parties to use, so I can't define what MPM
they use. I would like it to work in either case. I don't mind throwing in
locking logic based on the results of querying whether the MPM is threaded
or not - I just want to better understand that scenario and how it applie

them?

Hey all,
I am trying to port a module I wrote in C to one that uses mod_perl. The C
module would spawn a thread in the child_init process and poll a file. The
file polled contained data that the header parser phase would use. I
protected the data via a RW Lock.
Now when doing this in mod_perl
