Unless I misunderstand, they will evaporate only when the underlying
buffer content gets deleted to prepare the buffer for insertion of new
contents.  The old overlays/buttons are then completely useless to
keep around.

When they evaporate, they do it at a time when there is no form left
that could be working.

So I think the solution proposed by Masatake Yamato is the correct
one, unless I misunderstand the problem.
