Hello,
Is there any way to tell (besides looking at the sources) if a given SQL
plugin, or single methods of it, is reentrant/thread safe? The docs are
rather evasive on the issue ...
What would be allowed to do if I want to thread the SQL queries? Can I

like an event filter that'd be triggered after the event was delivered, but
I'm not aware of any such functionality. D
Hello,
Is there any way to inspect an event that was delivered, just after the
