Well... I've run reconstruct on large mailboxes before... and when 
things are normal.. I can look at a top listing and see reconstruct at 
the top the list.. using lots of resources while it runs.  In this 
case...  it's not using any resources.. it shows no evidence that it's 
doing anything.. and when I ctrl-c it... it exits immediately with no 
error messages. What could cause reconstruct to act this way?

I may try moving some stuff around by hand... as DL suggested... but I'm 
not crazy about that approach since I don't know the cause of the 
problem.  Part of me just wants to solve it the BOFH way to encourage 
the user to keep better control over their stuff... but for now I can't 
do that. 

Thanks,
Jared
