Internally there is a counter - and only one - the engine uses it too 
when it needs to.

The lock is dropped as soon as you get back to a wait with messages 
though (IIRC) (certainly the main runloop).

Unbalanced lock screens can cause problems though - the IDE has had a 
fair few in the past - it might still... Do you have an example of the 
abberent behavior you've seen? It would be useful to know if there is an 
engine issue lurking here, or a misplaced lock/unlock screen in the IDE.
