I haven't tried to address memory leaks specifically, but most of my
work has been fixing bugs have been latent for ages but weren't biting
us for one reason or another. For example:
* Clients weren't reconnecting properly if setvolume failed (as opposed
to the connection itself failing).
* FUSE wasn't updating to use a new graph in the proper place, causing
requests to be sent down to the old graph (where they'd get stuck).
Those might sound simple, but each required hours of debugging to arrive
at a diagnosis and fix - and there are several more. When I'm done
fixing these kinds of preexisting functional problems, I'll look into
preexisting memory leaks. Thanks for the heads-up.
