I think a sizable portion of the patch can be dropped if you do the
above. Namely the whole double init protection that got added in the
last round.

I think backdoor is a bit extreme. Yes it could allow people who
can set the plperl.*_init functions to muck with the safe. As an
admin I could also do that by setting plperl.on_init and overloading
subs in the Safe namespace or switching out Safe.pm.

Anyway reasons I can come up for it are:
-its general so we can add other modules/pragmas easily in the future
-helps with the plperl/plperlu all or nothing situation
-starts to flesh out how an actual exposed (read documented) interface
should look for 9.1

... I know Tim mentioned David as having some use cases (cc'ed)

So my $0.2 is I don't have any strong feelings for/against it. I
think if we could expose *something* (even if you can only get to it
in a C contrib module) that would be great. But I realize it might be
impractical at this stage in the game.
