Not crazy --- it was already mentioned.  It could probably allow using
--cat-blob-fd even on the platforms that don't inherit file
descriptors >2, though it wuld take some tweaking.  Though I still
think the way forward is to keep using plain pipes internally for now
and to make the bidirectional communication optional, since it
wouldn't close any doors to whatever is most convenient on each
platform.  Hopefully I'll hear more from Florian about this in time.

We're talking about what communicates between the SVN dump parser the
version control system-specific backend (git fast-import) that reads
the converted result, so that particular socket wouldn't help much.
