GDB locks RPM database

Thanks Jan.

Rebuilding rpmdb or removing locks would definitely fix the issue, but I just wanted to find out if there's any specific reason for locking.

I wrote the patch in 2008 using librpm:

I am not aware of such stale locks but then sometimes rpmdb stale locks could
happen even without any GDB involved and 'rpm --rebuilddb' helps in such case
(or just 'rm -f /var/lib/rpm/_*' but I am not sure how safe it is).
Hopefully it is no longer happening in new RHELs, I do not see it new Fedoras.

Anyway this is really unrelated to upstream GDB and such issues should be
filed through your RHEL support contact.

Still the librpm support is deprecated and no longer being developed as it is
being replaced by debuginfod support which already landed to upstream GDB.
