init ran out of file descriptors, spinning while trying to start a broken service

[Kai Groner]

After updating to 12.04 beta1, mysql service was broken.

I noticed my fan turn on a while after running sudo service mysql status (never completed).

:; sudo strace -f -p 1
Process 1 attached - interrupt to quit
pipe([1022, 1023]) = 0
open("/dev/ptmx", O_RDWR|O_NOCTTY) = -1 EMFILE (Too many open files)
close(1022) = 0
close(1023) = 0
pipe([1022, 1023]) = 0
open("/dev/ptmx", O_RDWR|O_NOCTTY) = -1 EMFILE (Too many open files)
close(1022) = 0
close(1023) = 0
pipe([1022, 1023]) = 0
.
.
.
^C

:; sudo ls -lv /proc/1/fd | grep -c /var/log/upstart/mysql.log
1005

I guess this is probably the same as #940290
