Good point.

Ctrl-T c to create an xterm window in Ratpoison.  You don't even need to 
exit mythfrontend.

Hmm, I must be doing something wrong because these work for me in 
runlevel 3 also. ;-)

No flame here.  The way Linux allocates memory you probably won't see 
any difference if you were just looking at the system memory 
usage/free.  It tends to use available memory for buffers and caches 
(which is not a bad thing, no sense in memory just sitting there with 
nothing to do!).  If you were looking at the individual processes, you 
should have seen a huge difference.  I don't have any info for KDE handy 
right now, but ratpoison is using 681K total, and one of my gnome 
systems is using about 310M by the time you add all the gnome processes 
together.  Granted my method wasn't all that scientific, I only added up 
the SZ column when doing a 'ps -elf', but still that much of a 
difference is huge.
