This would be my thought too. In general, any project I have done so far 
uses less than 2.5 G memory. Most modern machines can handle 16GB (I 
actually have 8)... most of my sessions probably don't need to access the 
drive while recording/tracking/mixing.

In my opinion, swap should show zero use during audio work. Even with 
swappiness set to 10 (some set it to 1 or 0) I have not had swap space 
being used. It is good to have swap enabled though, because if you do get 
there, at least you can save what you have done. I have found that in an 
OOM event it seems to be some part of the DE that gets kicked out as 
having not been used for a while which kills everything. Going into swap 
will hurt the current take (big time), but the system will at least still 
be running so whatever can be saved. Lots of snapshots is good too.
