This is a good point.

On the whole suite of tests (which includes the Graph and Template

Since test suites repeatedly build up and tear down data structures,
it seems to me that these would be great stress tests for a garbage
collector, but not very representative of the patterns of an average
php application. Do you have any performance/memory usage numbers
for something more typical like a WordPress index page request or
some such thing?
