longer time for that one to panic ("a few hours" compared to "a few
minutes" on my development machine).
I tried to reproduce this on a single-CPU machine without success.
But I only let the script run for ~1 hour, so I do not know if I were

I have not managed to create a small, simple, test program that
triggers this bug. But I have placed a tar-ball (PR44402.tgz) in
~kristerw at ftp.netbsd.org that contains everything needed to
