Sorry, yeah if I start up with jackd in realtime then I get the crash as 
described.  If I remove it the -R then startup works and I usually get a 
crash on sequencer exit - as described before too.

This has become a bit obfuscated because JACK's command line options are 
parsed in a weird way - hacking the .jackdrc file adding a "-R" to the end of 
line gets it parsed as part of the ALSA driver's arguments, if you add it at 
the beginning then it gets accepted ok.  Also when the sequencer crashes out 
jackd doesn't halt (when running in client-activated mode) so unless you're 
careful you can then change the command line options to JACK and think you're 
restarting it whilst it's already running (with old options).  Urch.

But yeah, I can definitely squeeze crashes out pretty much at will on the non 
capabilites kernel.  I think it's only fair I try out the proper CCRMA kernel 
now and see what happens.
