I tried few times, but to no avail. Looks like subtle race, bad news
for you, unfortunately.

*BUT*, after I pressed ctrl-c against mmap-sync in one of the torture
tests, the program stuck in down_failed (loadav += 2). Few minutes
later machine got very unstable and I decided to reboot it. Go figure.
