Since no one else has offered any...
Requiring explicit synchronization is fairly standard behavior, I see no 
reason to modify close().  I think some people get caught off guard 
because Microsoft DOS did not seem to have a filesystem cache, and even 
today Windows operating systems seem to always flush operations to floppy 
disks.  Of course if you power down a machine immediately after a write() 
call you will often see disk corruption, so either part of the Microsoft 
filesystem layer or the Microsoft applications treat floppy disks 
differently than non-removeable disks.  Anyone used to working on POSIX 
style operating systems is of course accustomed to mounting and unmounting 
disks, so I don't think it will be a surprise.
