I am confirming this only occurs with kwin, I used compiz and it didn't
leak memory for 12 hours.  I tried replacing kwin with compiz on a kde
session (it worked, mostly), had some compatibility issues, but I was able
to use it for several hours.  I later tried "unity" session with compiz and
many effects enabled: it worked just fine too.

Today I tried to wipe-clean my .kde directory, and refrain from changing
any settings.  I am still observing and will update.

Any ideas?
