Recently I’ve tried to change Shielded to use encounter-time locking. As opposed to the current implementation, which employs commit-time locking, this new version would lock an object on every write attempt. This would certainly speed it up, I figured. No IShielded would have to have thread-local storage for it’s temporary data – if a thread locks a field, it can write directly into some private members*. Commit time checking simplifies, knowing that every changed field must already be locked. Sounds great.
