Om has memory usage issues I'm trying to get to the bottom of.  Most of
it is used up by things beyond my control, which makes reducing usage
not very much fun.  Having Jack MIDI and being able to ditch Alsa would
drop the overhead quite a bit, for one.  So yes, that sort of usage is
typical, but definitely not good.

I havn't looked at lashd's mem usage whatsoever yet.  I'll take a look
at it when I get some free time.  Thanks for pointing it out.

Sorry for my bloatey software.  "Make it small" is somewhere after "Make
it work" and "Make it fast", and I havn't quite got there yet ;)
