...memory was at 166MB after the dispose()

Does the memory usage increase another ~166MB if you call process() a second time with the same file?  (Your original post sounds like it does, but just to be sure...)

The reason I'm asking is because memory might not be returned to the OS immediately, but just freed for reuse Perl-internally.
