I'm sure that the memory approach would be much faster as it had to do just one 
file system access intead of one per message. Though you're basically right I 
don't see the need to emphasize consistency in the trash folder as it could be 
easily retained by a re-index in case of urgency. And as the probability for an 
abnormal exit is rather small I'd strongly prefer the performance issue.
