Cannot post to twitter via Twitter-OAuth-iPhone in a NSThread

Question

I recently started using Ben Gottlieb's Twitter-OAuth-iPhone class to post status updates in app. I have successfully done so, when executed on the application's main thread. But, when I throw it in a "NSThread detachNewThreadSelector" the post never makes it to twitter. It processes fine and I get a proper [connection identifier], but the results never make it on twitter. Any idea how I can get this to run in a thread without bringing it back to the main thread?

Code added Tweet method

-(void)tweet{  
if([_engine isAuthorized]){
    [_engine sendUpdate:@"Tweeting"];  
}  
}  

Doesn't work:

[NSThread detachNewThreadSelector:@selector(tweet) toTarget:self withObject:nil];  

Does work (from main app):

[self tweet];  

Does work (from within a thread):

[self performSelectorOnMainThread:@selector(tweet) withObject:nil waitUntilDone:NO];
