--- Comment #1 from Ian Lance Taylor <ian at airs dot com> ---
I'm not clear: does the error "waitid: no such file or directory" happen
randomly, or does it happen every time?

It looks like calling the waitid system call is returning ENOENT.  I don't know
what that would happen.  Can you attach the output of `strace -f` for a failing
run?  Thanks.
