Just FYI in my experience on writing a Netty custom scheduler I had to implement on top of. JCTools algorithm (mpsc) a closeable queue for the per carrier run queue. You can find the code at https://github.com/franz1981/Netty-VirtualThread-Scheduler/blob/master/core/src/main/java/io/netty/loom/MpscUnboundedStream.java
And it was useful to have a precise semantic to allow VT bound to run on a specific carrier to make progress (or complete) once racing with their scheduler if latter is shutdown. disclaimer: I am one of the JCTools developers Il dom 11 gen 2026, 12:12 Michal Domagala <[email protected]> ha scritto: > Maybe a good idea would be `Thread.ofEphemeral()` ?
