The abort conformance test clicked before the pending Effect's fiber had started, so an early interrupt skipped onInterrupt and the test timed out (seen in release run 39104049541; nothing was published). The fixture now records started and the test waits for it before discarding the block.

Summary by cubic

Fixes a race condition in the abort conformance test that caused it to time out.

The test discarded the block before the pending Effect's fiber had started, so an early interrupt skipped onInterrupt. The fixture now records a started event before entering the pending effect, and the test waits for that event before discarding the block.
