commit 36f6874fcf5222f4553fb5b7782af18c7b6ea92a
Author: Panu Matilainen <pmatilai@redhat.com>

    Only muck with signals on first and last db open/close
    - Signals are per-process global, as long as there are other
      databases open (or references to the same db) we shouldn't mess
      with them. Less important on open, but if somebody is changing
      rpmsq-handling we shouldn't override that either.
