This is needed to ensure that pending updates are not lost due to the following scenario:

  • The loop executes the last iteration
  • There is more than one pending update or there is 1 pending update, but another is received when runAnActivityOrChildWorkflow is executing.
  • The workflow continues as new, losing all the unprocessed pending updates.

The sample code processes all pending updates even if their number exceeds the number of iterations. There is also a guarantee that updates are not lost due to a race condition between the update and the workflow calling continue-as-new. This is achieved by ensuring that the signal handler is always invoked before the main workflow coroutine is unblocked.
