Description

using a bounded queue with dispatcher.unsafeRunAndForget doesn't propagate back pressure and the dispatcher list of registrations will still grow unboundedly

the dispatcher docs use unsafeRunAndForget with an unbounded queue in the example, and it doesn't mention the bounding issue. A note or warning about that would be helpful

Research direction

Start by reading the dispatcher documentation and its example using unsafeRunAndForget with an unbounded queue. Update the documentation to warn that using a bounded queue does not propagate back pressure and that dispatcher registrations can still grow without bound. Done means the warning is clear in the relevant example or surrounding text.
