Rapid slowdown with 2.1.127 and 128

Machine is a Pentium (not pro or II) 120MHz with 32MB of RAM. 100% SCSI.

The last stable kernel on my system was 2.1.99, but that doesn't say much,
since I was too busy to even _try_ to run 100-126.

System runs nice and quickly until the kernel starts /sbin/init, then
starts going dog slow. Every new daemon that starts makes the system run
much more slowly (even though the daemon is marked as sleeping).
Sometimes I can go far enough to log in, sometimes the system slows down
quickly enough that my 5min timeout on my WDT trips and reboots the system.

It seems to have something to do with the number of process groups that
exist.

APM is disabled.

I'm still trying to track this down.

Starting in single user mode, I can usually get a login prompt, but
the first time I run a program it goes very slowly. Next time I run the
same program with the same arguments, it goes blazingly fast (obviously
a cache effect). ls in /proc takes around 4 minutes to start producing
output.
