Right also you can and will some day in time hit the same problem but
using rpm to do various queries will throw up the same error when using
yum because of the db lock.  I do not for see regular users encountering
this problem but heavy rpm -q, qa ,qi ,qiR, qf | grep foo will indeed.
I encounter it a lot of times especially when using multiple terminal
windows.  So I have to kill pid{rpm}.
