Dmitry Vyukov bf606094ee runtime: fix finalization and profiling of tiny allocations ... Handling of special records for tiny allocations has two problems: 1. Once we queue a finalizer we mark the object. As the result any subsequent finalizers for the same object will not be queued during this GC cycle. If we have 16 finalizers setup (the worst case), finalization will take 16 GC cycles. This is what caused misbehave of tinyfin.go. The actual flakiness was caused by the fact that fing is asynchronous and don't always run before the check. 2. If a tiny block has both finalizer and profile specials, it is possible that we both queue finalizer, preserve the object live and free the profile record. As the result heap profile can be skewed. Fix both issues by analyzing all special records for a single object at once. Also, make tinyfin test stricter and remove reliance on real time. Also, add a test for the problem 2. Currently heap profile missed about a half of live memory.
