// This adds 'beast' task which clones tests a given number of times (preferably
// constrained with a filtering pattern passed via '--tests').
// TODO: subtasks are not run in parallel (sigh, gradle removed this capability for intra-project tasks).
// TODO: maybe it would be better to take a deeper approach and just feed the task
// runner duplicated suite names (much like https://github.com/gradle/test-retry-gradle-plugin)
// TODO: this is a somewhat related issue: https://github.com/gradle/test-retry-gradle-plugin/issues/29
