I think it would be saner to give git-hash-object an operation mode
that makes it usable as a pipe-controlled daemon, so that one needs
not fork and exec for interning another object.  That way, porcelain
commands could keep one bidirectional pipe (feed object type and
source and whether to use -w into git-hash-project, receive object id)
to git-hash-object around until they finish.
