I’ll have to look at it but generally speaking virtual threads are not for us because they cannot be paused during blocking operations within the kernel space so you can’t have ten virtual threads blocked on a kernel action on a single process thread.
Java once had “green” threads back in version 3 or so but was removed and migrated to full threads.
