i've uploaded a new Tux patch to:

	redhat.com/~mingo/TUX-patches/tux3-2.6.3-B2

i've fixed all bugs in the gzip code i could find: made it use the 2.6
kernel's deflate library, and fixed a couple of bad assumptions. Memory
consumption should be lower as well, since now deflate state is
per-Tux-thread, not per-request. I've added the gzip fix from Miles Elam
as well.

i've done light testing with compression=2, but YMMV - does it work for
you?

i suspect the compression level should be configurable as well. Right
now it's hardcoded to level 6 - what level would be the best?

(this patch includes some more fixes as well - eg. stack footprint
reduction for CGIs.).
