> A queue is a reasonable option, yeah (they also have thread limits but they're much higher). Once we have custom executors they may be applicable here. It's also probably reasonable for most apps to block one Swift thread at a time, so having a singleton actor you run blocking stuff on isn't the worst thing in the world.

I hear mention of custom executors on several threads but there is nothing on the swift evolution and there has not been any activity on this [pitch](https://forums.swift.org/t/support-custom-executors-in-swift-concurrency/44425) either since year+ ago.  
Are there any blocking factors or is this feature not considered a high priority?
