I notice the same improvement, but give it time and the earlier symptoms
will come back to haunt you.. I get severe disk chompings, and erratic
mouse pointer movement every now and then.. My test was to load netscape
while playing mp3 audio.. In pre-2.1.89-3, the sound breaks up and the
moise pointer stops moving for periods of up to 2 seconds. In
pre-2.1.89-4, this works fine, HOWEVER loading gimp with netscape open and
sound playing I get a return to what happens in pre3 (eg having 10mb
physical memory free, eating more and more into the swap, and losing all
control over the system).

The scary thing is Linus said he didn't touch the swap code between pre3
and pre4...
