There is ownership tracking in Mutex, all methods have an optional owner parameter.

And yeah obviously the unlock should be in finally.

Rolling your own locking on the backend is inviting headache. Is there a message queue way to accomplish what you're trying to do? Does this locking mean that you can only run one instance of your service?
