Luc,

Cocoa now seems to be in multithread mode. However, I still get a crash on [pool release]:


    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    NSNotification *notif = [NSNotification notificationWithName:@"TextFeedCallback" object:nil userInfo:nil];


This (just like anything other but alloc/init, copy, mutableCopy, and new) returns autoreleased object. Therefore...

    [notif autorelease];


... this autoreleases the object second time, and therefore...

    [pool release];


... this fails.

Am I doing something wrong?


Yup: you forgot to learn the Cocoa memory management :)
