-/**
- * Event processor for reliably reproducing multithreaded apps race conditions in tests.
- *
- * The app notifies us about “events” that happen in its threads. The race condition test runs the
- * test action multiple times (aka iterations), trying to generate all possible permutations of
- * these events. It keeps a set of all seen event sequences and steers the execution towards
- * executing events in previously unseen order. It does it by postponing execution of threads that
- * would lead to an already seen sequence.
- *
- * If an event A occurs before event B in the sequence, this is how execution order looks like:
- * Events: ... A ... B ...
- * Events and instructions, guaranteed order:
- * (instructions executed prior to A) A ... B (instructions executed after B)
- *
- * Each iteration has 3 parts (phases).
- * Phase 1. Picking a previously seen event subsequence that we believe can have previously unseen
- * continuations. Reproducing this sequence by pausing threads that would lead to other sequences.
- * Phase 2. Trying to generate previously unseen continuation of the sequence from Phase 1. We need
- * one new event after that sequence. All threads leading to seen continuations will be postponed
- * for some short period of time. The phase ends once the new event is registered, or after the
- * period of time ends (in which case we declare that the sequence can’t have new continuations).
- * Phase 3. Releasing all threads and letting the test iteration run till its end.
- *
- * The iterations end when all seen paths have been declared “uncontinuable”.
- *
- * When we register event XXX:enter, we hold all other events until we register XXX:exit.
