Just out of curiosity, what's the slab? and what is the expected size
of it? I just checked mine and it seems to eat some 304596 kB
(2.6.14-ck4, soon 68d uptime). The only problems I've had recently is
firefox crashing more than it should (but it could simply be me having
a billion or so windows and tabs open, and it's the
mozilla-firefox-bin-1.5-r2 from portage which is masked ~amd64, so
it's probably just buggy - it dies with a segfault after beeing stuck
at 100% CPU for a while, cant see any OOM-messages anywhere), other
than that I've been able to both emerge stuff (nice'd though),
download stuff and burn backups DVD's with out problems -
simultaneously - and the system was still responsive :)

After all, if you are in school to study computer science, then a
professor saying:
"use this proprietary software to learn computer science" is the
same as English professor handing you a copy of Shakespeare
and saying:
"use this book to learn Shakespeare without opening the book itself."
