   There are 26 CI jobs with timeout-minutes: 60. Presumably this is excessive for most of them and they could be reduced.

   Most CI jobs are run with --fast-ci which runs tests in subprocesses with a timeout per process. IMO this timeout is more important than the outer timeout of 60 minutes. Examples:

   • macOS: Run 502 tests in parallel using 5 worker processes (timeout: 10 min, worker timeout: 15 min)
   • Ubuntu: Run 502 tests in parallel using 6 worker processes (timeout: 10 min, worker timeout: 15 min)
   • WASI: Run 502 tests in parallel using 6 worker processes (timeout: 10 min, worker timeout: 15 min)
   • Windows: Run 502 tests in parallel using 6 worker processes (timeout: 10 min, worker timeout: 15 min)

   --fast-ci also re-runs failing tests in verbose mode. It helps to ignore flaky tests and to get more information to debug failures.

   I don't think that the 60 minutes timeout is an issue in practice.

   Emscripten is different because it runs tests sequentially in a single process:
