commit a1c3537148a59f6a1c86ebcb686b2e2c8e404b5f Author: Alan Somers <[email protected]> AuthorDate: 2025-10-14 02:18:48 +0000 Commit: Alan Somers <[email protected]> CommitDate: 2025-11-06 00:25:19 +0000 fusefs: fix intermittency in the BadServer.ShortWrite test This test implicitly depended on the order in which two threads completed. If the test thread finished first, the test would pass. But if the mock file system thread did, it would attempt to read from an unmounted file system, and fail. As a result, the test would randomly fail once out of every several thousand executions. Fix it by telling the mock file system's event loop to exit without attempting to read any more events.
