Might be. But historically fuse had this behavior and I'd be very
reluctant to change that unconditionally.
With a systemwide maximal timeout for fuse requests it might make
sense to allow sync(2), etc. to wait for fuse writeback.
Without a timeout allowing fuse servers to block sync(2) indefinitely
seems rather risky.
Thanks,
