Are you sure you didn't muck something up in your profiling patch? I am
running 2.1.102-pre1 on a UDB, which is virtually the same as your
Noname (same kernel compile option). I tried the "gzip < /dev/zero >
/dev/null" and the above program, and nothing special happened. I did
these while running X and loading pages in the (DEC Unix version of)
Netscape, and there was only a barely noticable slowdown.

I don't speak for anybody but myself - that's enough trouble.
