I believe that PL_sv_placeholder is available for use, and won't show
up on any keys %INC

However, for maint I'd prefer a patch which doesn't change the semantics
of (what is visible by perl in) %INC

The current patch is backed out of maint (but still in blead)

As maint pumpking I'd prefer not to be the one interacting with future
revisions in the blead tree. I believe that there are at least 6 other
people on p5p with blead commit.
[I'd prefer to stay blinkered and just deal with p4 integrate commands]
