Modified Files: src/bin/sh: jobs.c Log Message: Avoid a core dump if a child process that is not one of our children happens to exit while we are waiting for another child to exit. This can happen with code like sh -c ' sleep 5 & exec sh -c "sleep 10 & wait !$" ' when the inner "sh" is waiting for the 10 second sleep to be done, the 5 second sleep started earlier terminates. It is a child of our process, as the inner shell is the same process as the outer one, but not a known child (the inner shell has no idea what the outer one did before it started). This was observed in the wild by Martijn Dekker (where the outer shell was bash but that's irrelevant).
