[Nix-dev] vserver and waitid returning pid - 1 instead of pid? Cause?

[Marc Weber]

Finally I've found the cause of my upstart problems.

This patch fixes the problem that upstart did'nt notice which child
process has finished.

+               pid ++; // why the hell doesn't this return the right pid?

the pid returned is the correct pid -1.

Any idea what might be causing this?
Can this be caused by using the wrong kernel headers?
