It could happen that an isolate gets stuck unable to exit if paused on exit when using Isolate.exit. Fixes https://github.com/dart-lang/sdk/issues/51164 TEST=isolate_exit_resume_test Change-Id: I114686ce0637434827e56988821932cb91238032 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/280044 Commit-Queue: Alexander Aprelev <aam@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com>
