Also it is a bit unsafe:

Hub, I am creating a dummy NSThread (which exits straight away), but I still get the same issues. Will still try looking deeper.
Also, I can’t use ‘local’ NSAutoReleasePool, since some objects might be allocated in one thread, but released in another.
Sorry for the confusion between ObjectiveC and FoundationKit.

I don’t know what exactly you want to do, but can’t you just wrap all calls to your entry points in pools?
You can use a local NSAutoreleasePool, it doesn’t matter in which pool actually deallocates the object (autorelease pools do not deallocate objects, they just call -release, which may or may not deallocate an object).

(and no, NSThread doesn’t create pools [why would it?], but it might be required to initiate a dummy thread to put the ObjC runtime into multithreading mode).
