Motivation: We're about to go on a sendability journey. Let's pick some low hanging fruit to get started. Modifications: - Add a few assume-isolated calls - Stop using static var - Use a dispatch group instead of a work item to wait for work to be done. Result: Fewer warnings

Nit: this should probably use the condition variable workaround we used in NIO to avoid triggering the main thread checker.

Potentially silly question but was this unsafe?

It's not "unsafe" per-se as neither .none case contains anything. However, Action isn't Sendable (and shouldn't be) so the compiler appropriately produces a warning here.
