Repacking many disconnected blobs

parsecvs scans every ,v file and creates a blob for every revision of every file right up front. Once these are created, it discards the actual file contents and deals solely with the hash values.

The problem is that while this is going on, the repository consists solely of disconnected objects, and I can't make git-repack put those into pack objects. This leaves the directories bloated, and operations within the tree quite sluggish. I'm importing a project with 30000 files and 30000 revisions (the CVS repository is about 700MB), and after scanning the files, and constructing (in memory) a complete revision history, the actual construction of the commits is happening at about 2 per second, and about 70% of that time is in the kernel, presumably playing around in the repository.

I'm assuming that if I could get these disconnected blobs all neatly tucked into a pack object, things might go a bit faster.
