i must say, Netscape 4.75 has been great for me ... especially with this
2.4.0-test8-vm3 kernel. No swap after opening and closing netscape numerous times
and browsing flash sites etc. the first time i've been in swap was 13 hours after
boot ...and that was after extensive hdd and ram tests along with compiling
freeamp and loading other mem hogging programs such as gtk xemacs21 and Q2 .
I'm very happy with this VM patch ...it seems quite stable. although i wont know
if it's any better than the old one until 2-3 days uptime ...which is when the old
kernel used to hit 100MB of swap and X would crash ... so .. we shall see
soon. BTW.. the test# kernels are quite stable as i've had test5 up for well
over 30 days at a time between power outages caused by lightning. I have
Bonnie++ scores that are kind of discouraging when it comes to file creations and
deletion. here are the scores.

this is on a pii 300 with 128MB sdram on a hdd with a 6GB ext2fs partition on a
7200 rpm UDMA 2 maxtor eide drive. ..netscape was not loaded but 9 Eterms, X,
gaim, xamixer, sawmill, apache, proftpd, and various other little apps were
loaded.
