Issues with rare use cases usually take many moons to emerge, but in
this case the complaints started right away.  So it seems like the
elimination of the loop interferes with non-rare use cases, which
means we will probably be seeing much more of similar complaints in
the future, including for stuff people do in their init files without
too detailed understanding of the underlying machinery.  I'd expect at
least some of these case not easily solved, and in any case it's a
nuisance to users and Lisp package developers.

What's more, a similar loop still exists on w32, so we will have
subtly different behavior on different platforms.

Reinstating the loop, but without the danger of inflooping, could have
taken care of these issues in advance.  Thus my proposal.
