Callback when a Mutex lock is aquired and/or freed

[Weissstreifen]

Hello everyone,

I currently have a problem with some instable commands running from my Kernel.php every few minutes. The commands must not overlap and may run between 5 to 30 minutes, depending on some external circumstances, so I execute them with the withoutOverlapping() method. Sometimes (especially during night times) the process gets killed by effects I can't control and the mutex does not get freed for the given duration. It would be awesome if I could hook into the lifecycle of the mutex and call a function whenever the mutex gets aquired or freed. Then I could build my own monitoring and alert system around this feature.

I know that I can pass a maximum time to live in the withoutOverlapping() method, sadly this does not solve my problem because I don't know if a lock got freed or died of old age.

I have not found anything related to it in the documentation, if such a feature does already exists I'm sorry for taking your time. Otherwise I'm happy to discuss.

Have a nice day!
