alas. i spoke to soon:

after i added a 6x1 convolver and an ambdec instance
jack2 bails out reproducibly after a couple minutes more, with a
"floating point exception". so more testing.

meanwhile, i'd like to know what these xruns are, and i wouldn't be too
surprised if the eventual crash is actually related to the message
buffer or some internal error counter wrapping...
