…#3717) ## Summary The `DeleteOldKeys` method was taking the lock for the duration of the keys deletion. This is not required, as the mutex really just need to be held to synchronize the list of participation keys. The underlying `OneTimeSignatureSecrets` already have a synchronization lock, which is taken as need. ## Test Plan Unit test added. The output of the test help to detect the timing issues addressed in this PR. Before this PR, calling Key() 10 times took 4.1 seconds. With this PR, it takes 255us.
