But waitid() with WNOWAIT doesn't work as one might expect from reading
POSIX: On Solaris 7, it returns -1 with errno = ECHILD although the process
is still present in the process table entry as a zombie (both before and after
the waitid() call). Likewise on OSF/1 4.0d. And on HP-UX 10.20, the code
that uses waitid() just hangs.

I thus have to disable this code again.
