Phil Pennock suggested I look at BSD::Resource, which seems to be a good 
fit.  Thanks Phil.

So, here's Devel::Memory.  It's very simple minded, and designed (hardcoded) 
for SVN::Web at the moment.  I'd appreciate feedback on any additional 
features that might make this useful (and a better name), as well as 
suggestions for a good API.

Here's the commit that created it:

     http://jc.ngo.org.uk/svnweb/jc/revision?rev=781

You can check out the code from that link too.

Usage is (assuming the directory is in @INC) just

     perl -d:Memory app-you-want-to-profile
