How much memory do you have in your machine? The "No Memory Lock" option
does just that, the audio application pages are not locked into real
memory (your real RAM), meaning they can be swapped out to disk when the
system runs out of memory. Which means you can get xruns due to that
(imagine: part of the app is on disk and maybe is needed again in memory
to run the realtime stuff and that's it, it has to come from disk to
memory and that takes a lot of time).
Maybe you didn't have enough RAM to accomodate all the audio apps and
their libraries. Wine or whatever cannot lock down enough memory and it
