Thanks, everyone, for the replies...

 So to sum this up I think there is not one scapegoat here, but many:

 1) FluidSynth could have better protection against many notes starting
 at the same time, but that requires some redesign unfortunately

 2) Jack could handle timing errors better, so things do not crash when
 it happens

 3) You could configure fluidsynth's polyphony to limit FluidSynth's CPU
 usage

  David, this appears to be a reasonable summary. It does appear that the
issue is not solely with fluidsynth, but the way fluidsynth and jack
integrate with one another. Are such shortcomings inevitable in the "do 1
thing but do it well" philosophy of linux apps (I hope not!) ? For instance,
it does appear unlikely that this would happen in an 'all-purpose'
applicaton like Apple's Logic Pro, for example...

...
  This sounds like it could be a good focus of the next
major version of
 FluidSynth.

  I would love to see that, Josh. For those of us who use linux in live
performances, it can't happen soon enough!

And thanks, Pedro, for forwarding my message to the fluid-dev list. I'd be
happy if constructive improvements follow as a consequence!

I will perform the stress test under the standardized/simplified conditions
that you describe, and get back to you. More about that in the next post....
Cheers,
