I think you have your models reversed. A reserved checkout model has
horrible scaling problems - people end up tripping over themselves
because they are doing parallel development. User K in Chicago
'reserved' a file and didn't finish his changes or went on vacation,
but User G in SF wants to do another change in that same file while
User K holds the lock. Oops. So, you force User G to break the lock.

Reserved checkouts may make more sense in smaller projects (where
ownership is well-defined), but almost certainly has no place in
large projects where ownership isn't as well-defined or
enforced. -- justin
