Comment (by warner):

 There are four test classes in test_web: Web, !IntroducerWeb, Util,
 and Grid. I ruled out Util and !IntroducerWeb (running them for
 several minutes in a row has a flat memory footprint). Running Grid
 by itself uses a bunch but seems to peak at 78M VMSize after about
 2 or 3 passes. Running Web by itself consumes more and more memory.

 I'm pretty sure this is due to the "all_contents" class-level dictionary
 in {{{allmydata.test.common.FakeCHKFileNode}}} and
 {{{FakeMutableFileNode}}}. I'll look into parametizing that with a
 container which can be discarded between test runs.
