I did see this problem and apparently it has to do with a combination of
opengl/motif/x issues. I have to do some followup on this as I though it
was only happening in my machine. Do you have X acceleration enabled?
What video card do you use? In my laptop there is some weird race
condition (have not had time to even try to debug this) so that
acceleration is not turned on after a reboot on the first login. Try
starting glxgears to see what sort of performance you are getting. In
that condition (acceleration not working) snd segfaults. If I logout and
login again (without rebooting) then glxgears reports good numbers and
snd works. Very very weird.

Same here, some issue with fweelin. That did not happen on the first
launch so it might have to do with wrong saved configuration settings.

I have not had freezes but the app is very experimental at this point.
For juggling delays I'd try sooperlooper.

That's not good. I'm having good performance myself. Have you installed
the kernel through the planetccrma-core-edge meta packages? If so, what
does /etc/rc.d/init.d/rtload status reports? Have you set up the
priority of jack to, say, something like "60"?
