So yeah, I had to find where I put this little nugget, but you're right 
- data!  General deductions, linux runs a lot of crap in the background 
with a general UI, in this case kde, but I have about every desktop 
installed.  I sadly deduced they all suck in some way, but kde tends to 
suck less.

This was after chromium was found chewing up a good 14gb of ram an 
executed already, and chrome killed too (I use both, I have to keep some 
important apps running in chrome for when chromium dies).

Some fun facts:
