    Wow, thanks a lot for pushing this forward! 
    
    I planed to put an enhancement into original path, but got stuck up with other things.

    
    In InterProcessMutext, I would love to have a (public / protected) method which can returned
a path to an actually owned lock znode (LockData.lockPath) of a current thread. This would
enable to build a pattern over a lock which could guard for the case of lost lock and initiate
an abort of currently running task.
    
    What do you think?

> I have a need for a durable InterProcessMutex. Main reason for this are processes with
critical sections, where I can not afford to loose a lock due to session expiration. In such
case, others might acquire a lock and kick in while the previous process is still running
but e.g. experiencing connection issues. To kill this temporally detached process in favor
of others would be too costly.
> To achieve such behavior, I need lock nodes to be created in PERSISTENT mode. This is
not possible to do easily with currently implementation of locks due to few internal scoped
classes and methods. I would like to change this.
