The docs on this patch need some cleaning up and expanding:

    * The possible insecurity of %_SHARED needs expanding.
    * The docs still refer to plperl.on_untrusted_init
    * plperl.on_plperl_init and plperl.on_plperlu_init can be documented
      together rather than repeating the same stuff almost word for word.
    * extra examples for these two, and an explanation of why one might
      want to use each of the three on*init settings would be good.

I'll continue reviewing the patch, but these things at least need fixing.

cheers
