I would guess that the problem doesn't occur in the vfork() call
itself, but in the child process (gzip?), and there's a problem
that causes the child to be incompletely divorced from the parent.
Is there any trick to reproducing this problem? I just did a make
universe on i386 and didn't see it, but maybe my sources are too
It would be interesting to see if fork() fixes the problem. With
the VM optimizations, vfork() is only about 20% faster than
fork(), so build times shouldn't be significantly impacted.
