A session isn't all that much. It mostly contains an EC, some pointers and the
(limited) stack of pages.
It's only when you have a bunch of EOs in the session EC that they get heavy.
Try it: make an empty app, override Session() to include a counter, use "ab"
with ab -c 5 -n 5000000 and check when you get an OOM.
Cheers, Anjo
