So the script is run with SIGALRM blocked (as can be seen in /proc/$$/status, "SigBlk: 0000000000002000"). One reasonable example of where this bites is an interface up script that calls ping with a timeout to give things a chance to settle down before continuing, but abort if this doesn't happen within a reasonable time). Since ping uses SIGALRM for the timeout, this now never terminates. - -qemu-0.14 didn't block SIGALRM, so such scripts worked fine there. \ No newline at end of file |
