Hi @tboogh Thank you, it sounds great! I will take a look once I'm back from conference travels! I discussed the approach with people at the conference, and one suggested looking into OSUnfairLock for performance. Not that I think it matters for tests, but maybe food for thought? https://developer.apple.com/documentation/os/osallocatedunfairlock |

This is a proposal to make the access to the
Mockthread safe so that it can be used in tests read/write mocks concurrently. TheNSLockensures that access to the calls dictionary is safe. We have used a similar approach where we used adispatch_semaphorebutNSLockfeels like it's a cleaner approach. This should solve the problems discussed in issue #20.The test written is a quick an dirty way to replicate the issue in a minimal way.
