Not necessarily.  A regular user can run rpm -q since it doesn't lock 
the database (your original posting showed rpm hanging on a FUTEX).  I 
don't know rpm internals but I'd guess that simple queries for a 
specific package or even a listing of all packages don't go very deep 
into the rpm database.  Also, since the database isn't being updated, 
there isn't any need to lock the database during the query.

Cheers,
Dave
