Won't make a difference in Om's case, since om_gtk isn't even a Jack
client (it doesn't do anything with audio at all, actually).
On my machine, Om used to consume 56MB after starting om_gtk (which
launches the drivers and loads plugins etc), now it's down to 23MB. Not
as good as I would like, but a pretty good step in the right direction
anyway.
