I have been plagued with little xruns for a while now, and couldn't
figure out why! I'd seen something on using /tmpfs, but for some odd
reason I thought it was for people using a journalled FS on their root
filesystem. Duh!
I applied this this morning, and have been recording some things, and
have not seen a single xrun during recording!!! Woohoooooo! Hopefully
this puts an end to that little problem.
Thanks, Patrick!
