We should only setup the goroutine after we've grabbed the lock to safely start the watcher.

Additionally, the watcher should only be retried if we're not interrupted and shutting down for example.

  • If a new flag is being introduced, review whether it is really needed. The flag names should be clear and intuitive (as far as possible), and the flag's help should be descriptive. Additionally, flag names should use dashes (-) as word separators rather than underscores (_).

New/Existing features

  • Should be documented, either by modifying the existing documentation or creating new documentation.
  • New features should have a link to a feature request issue or an RFC that documents the use cases, corner cases and test cases.

Backward compatibility

  • Protobuf changes should be wire-compatible.
  • Changes to _vt tables and RPCs need to be backward compatible.

We should only setup the goroutine after we've grabbed the lock to
safely start the watcher.
