[jira] Resolved: (MODPYTHON-8) Improve apache.load_module with a
two-level locking scheme
[ http://issues.apache.org/jira/browse/MODPYTHON-8?page=all ]
Graham Dumpleton resolved MODPYTHON-8.
--------------------------------------
Resolution: Fixed
Resolved by new module importer for 3.3, but for 3.3 release looks like the new importer will have to be enabled explicitly as will not be the default.

> We should rewrite apache.load_python with a two level locking scheme, in order to reduce thread contention when using the threading MPM.
> I've already implemented something similar for a custom-made publisher system (comparable to Graham's Vampire) ; I've used a thread-safe caching system that I've donated to the Python Cookbook :

> Maybe this should be experimented in a separate branch, and merged back once we're sure that everything works perfectly ?
