Maxim Konovalov 19d099fc86 o Now when SIG_IGN signal action for SIGCHLD reap zombies 
automatically it is possible wait4(2) returns -1 and sets
errno = ECHILD if there were forked children.  A user can
set such signal handler e.g. via ``trap "" 20'', see a PR
for the test case.  Deal with this case and mark a job as
JOBDONE.
