I've witnessed this same behavior on my 8 meg machine as well. A previous
message suggests it may be the system software, and I agree, but I was
wondering if it could also be a cdev or DA?  Since they are called by the
Finder, would they not have a better chance to leave locked memory blocks
lying around?   Is the cleanup of the Application heap in applications now
attempted in some form on these finder-related operations?
