OK, but it deadlocks when we write, unless we use "sync" option, which 
hurts the performance.

As mentioned by Rajesh Amaravathi:

	"This is a problem generic to fuse/userspace filesystems."

Mid term, are there any plans to deal with this problem?

I understand the fix may need to be partially done on the kernel side, 
but it would be very beneficial to glusterfs.
