Accommodate systems with very large databases and slow disk/cpu (#38947)

Browse Source 
On startup we run an sqlite3 quick_check to verify the database
integrity. In the majority of cases, the quick_check takes under
10 seconds.

On systems with very large databases and very slow disk/cpu,
this can take much longer so we freeze the timeout.
