The reason is - if mount is not sync, something is writtent to the device, 
and then device is removed before it is manually unmounted AND unmount 
syscall completes, then device filesystem will become broken, possibly 
unrecoverable.

Since users don't like to manually unmount their devices, and developers 
really don't like when users blame them for unrecoverable data loose, 
default is to mount sync.
