As Brandon mentioned, I think "oidmap" should be the new data structure
of choice (with "oidset" modified to use it).

object_length is defined to be "unsigned long" in Git code, I think.
When is object_length not known, and in those cases, would it be better
to use a separate data structure to store what we need?
