Description of problem:
When I do the following:

Terminal 1: 
    rpm -qa | more  (and don't go thru all the output but leave it 
                     at page one)

Terminal 2:
    rpm -e "some installed package" 

The "rpm -e" command will now hang indefinately and will have to
be killed with a 'kill -9 <pid of rpm -e>'. If I now quit the rpm -qa
on terminal 1. A repeat of the 'rpm -qa | more' command will now
also hang. I now have to:
rm -f /var/lib/rpm/__db.00*
rpm --rebuilddb

to get rpm -qa working again. Just doing the 'rpm --rebuilddb' without deleting 
the __db.0* files will result in a hang of the rpm command. 


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. rpm -qa | more (on terminal 1)
2. rpm -e <some rpm> (on terminal 2, after starting rpm -qa on terminal 1)
3.     

Actual Results:  The rpm database got corrupted

Expected Results:  I think it just should have deleted the rpm in question.
