i have 512mb ... and the system never seems to approach using even half
of that ...

hmmm, i'll test out some vst's other than crystal synth with memory lock
enabled and see how they go ... as for ram, i don't think my system has
ever even used the swap partition ...
unless - and i have no idea here - my system is blocking some libraries
from accessing ram while realtime caps are enabled?
