Wait instead of wait. And it is missing a . in the end.

Can you squash your commits?

Should this be TransactionTimeout? We've got Deadlocked, but that seems to be an exception.

What you recommend it to be? LockWaitTimeout?

@matthewd

@rafaelfranca either one seems fine to me. TransactionTimedout sounds less consistent... I think the noun form fits with wider exception naming: it's FrobError, not FrobFailed. It's a fairly fine distinction, but I think an exception describes what occurred that prevented the action, rather than why the action couldn't be performed.

Yeah, it makes sense. I think TransactionTimeout is better than LockWaitTimeout since it is more generic. @gcourtemanche can you rename the exception from TransactionTimedout to TransactionTimeout?
