Hi Ralph,

I'd like to fix this.  There are several threads spawned by various synApps modules.  I'll read the 3.15 docs and see how to comply.

Subject: Autosave and IOC shutdown

Hi Tim,

EPICS 3.15 is trying to make it easier for an IOC to cleanly shutdown.
It add tests and better control over shutdown hooks.
Autosave, on the other hand, starts a thread - running the
save_restore() function - that is designed to never shut down.

That seems like a clear conflict of interests, that shows as frequent
error messages on shutdown:

> A call to 'assert(dbLockIsInitialized)'
>     by thread 'save_restore' failed in ../../../src/ioc/db/dbLock.c
> line 255.
> EPICS Release EPICS R3.15.0.1-DEV $$Date$$.

(Autosave trying to use cleaned-up stuff in Base.)

Do you have any thoughts on this?

Cheers,
~Ralph
