To answer your question, the library is updating the cache each time a
package is installed or removed.
A database can only be closed if the frontend requested it
(alpm_db_unregister), or if the library resources are released
It would help to get the whole set of debug logs (set the PM_OPT_LOGMASK
option to 0xFF) to have a better idea of what's happening.
