   + cf701eb:
     Fix performance regression on builds that change a test
     configuration flag.

Important changes:

  - On Linux, the default limit on the number of `--watchfs` file
    events per directory has been raised to 10,000 (from 500). If
    needed, it can be increased further via
    `--host_jvm_args=-Djdk.nio.file.WatchService.maxEventsPerPoll=<lim
    it>`.
