[SR-Users] 500 Forking capacity exceeded (12/SL)

[Jorj Bauer]

Sadly, the branches are tracked in a 32-bit number, so you can't make it to 40. (We use 30 at Penn, having found a couple bits reserved.)

We've done some preliminary work trying to migrate this to a 64-bit, but it's not complete, and we're not actively working on it any longer.
