> [Transaction
> IEP|https://cwiki.apache.org/confluence/display/IGNITE/IEP-91%3A+Transaction+protocol#IEP91:Transactionprotocol-Uniqueindex]
> contains an operation that need a short term locks (look at insert operation
> for sorted index), but this type of lock lies on present implementation
> badly. Today, if a transaction releases a lock that has been got to twice
> (maybe different types, but in one key) the lock is released at all.
> Adding counters by lock types is solved the issue, but possible it is not
> required to solve the problem, because we can change operation in order of
> the short term locks will be not needed.
