I think it might be already possible to get the same behavior with something like a read-write lock. Essentially if you want the blocking behavior above then get the write lock, and otherwise get the read lock right after entering the `limitedParallelism` context. This way the write lock avoids other coroutines from touching the data in my object while the first coroutine suspends. But I think the virtual threads + coroutines version is much cleaner and more efficient.
