This is my TEST 4, with no X, KDE, etc.

Logged in a VC and ran leak.

Try to log into another VC and:
-----------------------------------------------
Welcome to Linux 2.1.124.
wolverine login: ds
/bin/login: can't map '/lib/libc.so.5'
/bin/login: can't map '/lib/libc.so.5'
/bin/login: can't load library 'libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't load library 'libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't load library 'libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't map '/lib/libc.so.5'
/bin/sh: can't load library 'libc.so.5'
Unable to load interpreter
INIT: Id "c3" respawning too fast: disabled for 5 minutes
--------------------------------------
The system remained responsive (however I can say that it had the same
behaviour some kernel releases ago) but I wasn't able to run anything

I could switch to the VC running leak an press ^C.

The system is ok, I logged in, run xinit and I'm using netscape to write
this.

Im starting to have doubts if the patch was applied correctly, but I
applied the patch, ran make dep and make bzImage. The timestamps seems
correct and the image was created ok.

I'm not sure what's hapenning...

Is this the expected behaviour?
Am I doing something stupid?

I will do a few more tests and if I find anything usefull I will report
it.
