Apache::Reload shouldn't be used on production systems. At least in the
way you describe. This dissolves the problem.

I already handle this in my own code in a system with pluggable user
modules. I want to control myself if the scripts dies (which is does on
system modules) or not (which it does not on user supplied modules).

I do not want Apache::Reload to remove this control from me, and I do not
under any case want old code to remain in memory or be removed, and
execution continue, when I have given a "reload" command. That would be a
major security risk.
