Let's say we are creating a handler and this handler died but
was able to create another one. This another handler can cause
some damage, do things it isn't supposed to. I understand that
it isn't the case currently, but it will be with asynchronous subs.

I think it's possible to make perl modules behave more like
native modules, even create configuration directives.
This will enable anyone to do much more much faster,
which is the whole point of embedding perl I believe.
