For the specific case of mod_perl, would it be more useful / efficient
instead to have a C-level hook; eg register a C-level function to be
called each time an object is cloned? Or perhaps have a new 'clone' magic
type that can be attached to an SV which points to a cloning callback
function ???
Stas, I don't know what specific activity you need to carry out during
cloning, so I'm just vaguely hand-waving here. In particular I don't know
whether you need to call Perl or C code.
Anyway, I've got some spare time at the moment, so I might be volunteering
to take this on (assuming we can all agree on the interface !)
