Subject: Monitor / *Scope(exit)*
Hi Frank,
at least this makes me think :

http://www.digitalmars.com/d/exception-safe.html

especially :
void abc()
{
     Mutex m = new Mutex;

     lock(m);    // lock the mutex
     *scope(exit) unlock(m);    // unlock on leaving the scope *

     foo();    // do processing
}

and :
http://www.digitalmars.com/d/archives/digitalmars/D/learn/Thread_synchronization_5382.html

Given:

synchronized(obj) { ... }

You can consider the opening brace of the synchronized block to be
equivalent to a mutex lock operation where obj is the mutex being
locked. *Exiting the scope* of a synchronized block by any means 
releases the lock.
Hope this is usefull , Bjoern
