How very important!   If you don't believe that delayed-write is 
working, try mounting a USB fs (one that uses a solid-state memory, like 
Compact Flash or Smart Media),  copying several MB of files from it to a 
hdd, and note how slow it is.   Then delete all the files on the USB 
device, and copy all the files back.  The copy is done almost in an 
instant!  But then, when you unmount it, you can see it take several 
seconds to actually write the files from cache.  So if you yanked it out 
without unmounting it, you wouldn't really have anything.
