 My proposed solution is to put the require inside an eval.  Upon failure,
 simply write to the error log.

 My Question:  If the require is in an eval, what happens when a reload
 fails?  Does the old code in memory stay or or is it removed w/out being
 replaced by the updated code?

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.
