Hi!

I've seen this for some time now, even before the upgrade to rpm 4.4:

While upgrading the system urpmi is sometimes just blocked, with no
obvious reason (thus my guess is some race condition). I'm seeing this
normally when update-menus is also running.

lsof shows:

# lsof /var/lib/urpmi/.RPMLOCK
COMMAND     PID USER  FD TYPE DEV SIZE   NODE NAME
urpmi     24707 root 5wW  REG 3,2    0 727937 /var/lib/urpmi/.RPMLOCK
update-me 25083 root  4u  REG 3,2    0 727937 /var/lib/urpmi/.RPMLOCK
urpmi     25192 root  5w  REG 3,2    0 727937 /var/lib/urpmi/.RPMLOCK

strace for urpmi (24707):
read(7,  <unfinished ...>

strace for urpmi (25192):
futex(0x95ca2d0, FUTEX_WAIT, 1, NULL

and for update-menus:
flock(4, LOCK_SH

So both seem to be locked. I'm not sure if update-menus has anything to
do with it, but as I said, I've only seen that so far when update-menus
is also running.

I've also files a bug report for that:
