No worries--especially since it's not getting into swap (and sometimes 
using swap isn't a problem).  It's just caching information that was 
read off the disk in case it's accessed again to save hard drive access 
time.  Linux does this (not Myth).  After all, you've got the RAM, and 
if it doesn't get used, you've wasted money buying it, so Linux makes 
sure you use it.
