Just want to say I have been busy this week and am out next week, but I will get to this, and thank you for your contributions!
Detects and prevents deadlocks during the library misuse, eg. by injecting code into the critical sections that itself might want to obtain the relevant lock. A follow up to prometheus#1076. Signed-off-by: Przemysław Suliga <mail@suligap.net>

It's hard to justify the overhead of double locking there. Signed-off-by: Przemysław Suliga <mail@suligap.net>

No worries, nothing urgent here and thanks. I thought about it a bit more and ended up pulling out the deadlock prevention from the "hottest" path: metrics.py and values.py. It's quite hard to justify the overhead of this double locking approach there. But I think it's not an issue in registry.py.
