API

fn = debounceify(asyncFunction)

Debounces the asyncFunction so that

1. No parallel executions of asyncFunction will happen
2. Debounces the stack, so if 10 calls happen while asyncFunction is running only one more will be triggered when it finishes.
3. Forwards errors and return values.

debounceify.running

The active running job, null if none.
