This sort of change has me wonder why it was a weakref in the first place – probably for a reason?

Same concerns here as @akx. We need to ensure with a test that it doesn't create a circular reference and prevents garbage collecting unused SentinelConnectionPool objects.

But isn't it already covered by current tests in test_sentinel.py? I mean, GC is always take in action after the tests been executed. I also had a doubts about this, but I didn't find any reason why weakref was used and current tests works as expected. Do you have a specific test case in mind that is worth to add?
