Yes.

File-based products cause in-memeory registries to
get populated on process startup.  This has nothing to do with
and is not affected by database changes.

No.

No.

Because there are two registries involved. The database stuff
is replicated. The file-based information requires restarting
to get updated.

Because the icon is loaded into the url space during process startup.

I'm afraid so.
