Yes, that one is about a year old, and caused me to actually fix some
things. I couldn't reproduce any problems with it after that, at least not
attributable to %fs/%gs.

I tried to compile this version with my current library setup, and it
eventually will exit printing a line of "(null)", but that appears to be a
serious bug in the test-program rather than anything else. It waits for
the cloned process using WNOHANG, but then re-uses the same stack for the
next child, even though it's already in use.

That stack re-use bug certainly can cause anything. But I think I've seen
a better test-program from Uli that actually did something.
