>Correct you can't steal the carrier thread from an Object.wait() waiting virtual thread. This is apparently in the pipeline but it is a pretty major limitation.

I mean stealing other virtual threads from the pinned carrier thread (except for the one pinning it) so they can make progress. Normal work-stealing stuff - the queue(thread) is blocked(pinned), so process that task(virtual thread) in a different queue(thread).

It makes sense that a pinned thread remains pinned with the virtual thread that pinned it.

The 256 default carrier thread limit is going to frequently be a problem though, yeah. That's more than enough to cause all this, and it's a pretty crazy default imo.
