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,
Miklos
