I have two scripts that post messages each other. Scripts' on_message functions look ugly and unreadable so I decided to rework them using flow.

My old code usually posts and receives a few dozens messages in a single frame.

I found that flow.until_message waits for next frame after receiving the message. Therefore my new code requires a few dozens frames to complete --- this is too long for my game.

Is it a flaw by design? Can it be fixed? flow makes code look so much readable...
