Actually.  If jackd crashes, messages in jack control will not give you
the entire output.  That's because jack control loses the handle before
the core dump.

And increasing the periods/buffer did nothing.  Continues to crash.
Wouldn't matter anyway, because even in non-realtime mode, I can't
connect anything to the jack daemon.

I think I am going to dump the 64 bit version of ubuntu studio and go
with the 32 bit version.  The only way the 64 bit version seems
reasonable is if I compile everything and I might as well use Gentoo for
that.
