Comment (by nickm):
>My first idea was to store them compressed, so we wouldn't need to do on
the fly deflation, but that'd mean they don't compress too well.
Maybe we should look for designs where a bunch of clients will wind up
requesting the same sets of descriptors? That might help. Could be
tricky, though, and it would represent a big divergence from our current
design.

oomkiller before?
Or we could change the settings if we are close to the memory limit. But
I don't know whether that's a such win: we'd be using more bandwidth that
way.
And maybe we could retain the current settings, but limit the number of
descriptor downloads that we support concurrently.
