--- Comment #9 from Blou <philippe.blouin at inlibro.com> ---
I would favor option 4, and option 2 as a lesser evil scenario.

We use the database everywhere, we keep trace of everything in it, including
deleted objects, and can use it to retrace everything that happened to a
library when they ask.  


And then we use an outside tool for messaging to a background worker coded
by/for Koha, for tasks where a nanosecond reaction time is absolutely not
necessary.



MQ (and Erlang) is surprisingly demanding on ressources for the little it
offers.
The last two releases, I've hacked the background_jobs tool to make sure the
database was always used, and checked at startup, so that no task was lost. 
You sure can invest a lot of efforts to correct MQ, but why?  What is the long
term objective for this?  Because background tasks are sure not enough to
justify the added complexity.
