Execute WordPress cron events in parallel, using a custom post type for event storage.
Using REST API endpoints (requires WordPress 4.4+), an event queue is produced and events are triggered.
## PHP Compatibility
Cron Control requires PHP 7 or greater to be able to catch fatal errors triggered by event callbacks. While the plugin may work with previous versions of PHP, internal locks may become deadlocked if callbacks fail.
## Event Concurrency
In some circumstances, multiple events with the same action can safely run in parallel. This is usually not the case, largely due to Core's alloptions, but sometimes an event is written in a way that we can support concurrent executions.
