No.  The infrastructure for the controls should take care of that.  I
haven't read the code that well after the latest changes; you should see
what happens.  Since both ppolicy and syncprov do register controls, and
they work pretty well, I don't see why yours shouldn't.  Can you
cross-check if you did anything different in this sense?

The configuration parser has undergone lots of changes recently; issues
are being reported (see the latest 8-10 ITSes); it is very likely that you
spotted yet another.  I suggest you dig as much as you can to trace the
origin of the problem, and then file an ITS, so that the problem is taken
care of using the regular track.

If you think the dynamically registered controls are suffering from a
problem as well, please file another ITS.
