I don't know whether this was discussed at some point or not (couldn't find anything when searching my mail though) but I'm guessing this is the reason I get tons of complaints of memory leaks printed to the console with 5.1. While I agree with the intention (memory leaks should be fixed, not hidden) I'm wondering whether the approach here doesn't take things too far.
First of all, my understanding is that if you create your own threat then you *have* to create a release pool for it. Especially considering that some of the complaints I seem to be coming from Cocoa itself rather than objects Allegro creates and then leaves dangling, I suggest that we restore the release pool for the mangled main (see patch below) and drain it periodically (not sure how to do that though).

If I'm missing something and Allegro itself is actually leaking objects, does anyone have a suggestion for where to start looking for places where one might fix "Object of class NSPathStore2 autoreleased with no pool in place"?
