A lock another open holds fails at once with file in use instead of parking
A contended lock parked until the holder unlocked, but through a kernel
or FUSE mount the kernel serialises writes to one file, so the parked
lock held up the holder's own unlock and close on that ctl, and the two
deadlocked. acme's qlock blocks; here the second lock is refused at once
with file in use (EBUSY) and the client retries, and nothing parks on
the lock any more.
