• Add static executors, which are an optimization over executors that are kept
  around forever. (Static Executors #112)

@taiki-e Any chance you can review this? This is blocking performance improvements in Bevy.

(If you don't have time it's already been reviewed by other members so I'm fine publishing this.)

around forever. (#112)

Is it confirmed that the performance issue is not handled well by inlining?

When I received a similar request on crossbeam before, it could be handled almost well with inlining alone.

Apparently the core issue was the locking of the Mutex used to abort the task when the Executor is dropped. When this Mutex isn't being locked Bevy has observed noticeable performance gains.

Oh, that indeed cannot be handled by inlining.
