The opfs-wl lock hang has been traced to starvation between the WebLock and the tight wait-on-VFS-calls Atomics.wait() loop. This can reportedly be resolved with another level of indirection in which the WebLock takes over the wait-on-VFS-calls part until it's unlocked, returning to the global loop when it's done. That exceeds this morning's ambitions but is next to try out.
