SubjectRe: 2.6.35-rc3 deadlocks on wakeup(?) (was on semaphore operations)
Same thing happens with fakeroot-tcp. So it looks like it is not the
semaphore ops but the wakeup logic.

In one case processes wer waiting in sk_wait?? or so and one sees

libfakeroot: read: Connection timed out

after awhile. Wereupon the build continues for a while until it hangs for
good.

Another run resulted in hangs during futex wait:

$ strace -p8015
Process 8015 attached - interrupt to quit
futex(0x2b6bd51d0640, FUTEX_WAIT_PRIVATE, 2, NULL

There are always some zombies around when this occurs.

0 1000 8015 7712 20 0 18632 6796 futex_ S+ pts/0 0:00 /usr/bin/make -f scripts/Makefile.build obj=drivers/net
0 1000 8239 8015 20 0 0 0 exit Z+ pts/0 0:00 [make] <defunct>
0 1000 8240 8015 20 0 0 0 exit Z+ pts/0 0:00 [make] <defunct>
