But it should never change the behavior.

Thread handles are reaped when apr_thread_join() is called, which is how you
'harvest' now-dead (or soon-to-be-dead) threads.

It looks like you have a non-ASF module creating threads frequently, from the
users@ list post; I didn't see a ton of dups in that list.  Don't forget you
have to free them, if you are the author of the module.

If you are using third party modules, you keep forgetting to mention which one(s).
