Thanks for looking into this, Jeff.
Two questions:
1. Does this mean there are potential problems with other git operations
that involve ref negotiation, not just when doing git clone --reference?
Is there a chance to run in to this deadlock by doing an operation like
"git remote update"?
2. If we configure the webserver to serve some files directly, without
passing them to http-backend, e.g. doing the recommended apache magic:
> AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$ /var/lib/git/$1
> AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /var/lib/git/$1
> AliasMatch ^/git/(.*/refs/heads/.*)$ /var/lib/git/$1
Will that make the spooling less of a problem, since it won't involve
the super-huge files?
