> *Motivation:*
> We have an embedded deadlock prevention strategy (presently, it is _Wait-Die_). Although, [the original paper|https://dl.acm.org/doi/pdf/10.1145/320251.320260] about deadlock prevention contains another two strategies: _priorities_ and _Wound-Wait_. Also, the mechanism should give a possibility to not use any strategy to prevent deadlock.
> All told, above shows we need to separate the prevention strategy in dedicate interface (which even has one implementation _Wait-Die_).  Another implementation will be released by necessary.
> *Definition of Done:*
> A deadlock resolution strategy (_ResolutionStrategy_) has to be extracted to interface, which parametrizes _LockManager_. Wait-Die strategy (_WaitDieLockResolutionStrategy_) will be the only one implementation of _ResolutionStrategy_.
> _HeapLockManager_ should be parametrized by _WaitDieLockResolutionStrategy_.
