Description of problem:

Installed fresh rpm 4.4.2.1-0.2.rc1 with yum update, then on first rpm command
after the update I get:


$ rpm -Uvh  /usr/src/redhat/RPMS/i386/lshw-2.10-2.fc8.i386.rpm
/usr/src/redhat/RPMS/i386/lshw-gui-2.10-2.fc8.i386.rpm
Preparing...                ########################################### [100%]
   1:lshw                   ########################################### [50%]

and hangs forever, strace of the rpm process gives:


$ strace -p 7886
Process 7886 attached - interrupt to quit
futex(0xb7bab4ac, FUTEX_WAIT, 1, NULL


Trying to kill:

1 - Ctrl-C don't help
2 - kill <pid> dont help
3 - kill -HUP don't help
4 - kill -9 killed it.

Then did

$ rm -rf /var/lib/rpm/__db.00*

and now the rpm -Uvh works, some rpm -e/rpm -Uvh also works.
