What is the motivation behind this feature request? Is your feature request related to a problem? Please describe.
If you have multiple repos running on the same machine, it would be convenient to be able to easily identify which pid corresponds to which repo.
Describe the solution you'd like
repo.lock is currently an empty file. I think it should contain the PID.
Describe alternatives you've considered
While you could get the PID from programs like ps, when the repo is already running it would be convenient to find the PID, which can then be checked to see if the process is still running.
Additional context
I am writing a few tools that start and stop these. Normally they might be longer-running but for my use case they won't run very long. One failure case happens if the repo is already running.
