Might be showing off my lack of unix admin knowledge here but using 'top', it's the value of the 'virt' column - ie. the biggest possible process size if the whole thing was resident. I've been using it to work out how many clients I should limit apache to, but looking at it the 'res' figure never seems to get anywhere near the 'virt' figure. Time to rewrite my assumptions I think!
I get about 90 MB "virt" (70 MB "res") per process, running some pretty heavy custom mod_perl templating software with some AJAX stuff that uses (gasp) Python as a back-end via mod_python, along with DBI (DBD::Pg).
Sometimes, the load average hits 6.0, but everything always seems to load quickly enough. :)
