sync(2)

[Reini Urban <rurban at x-ray dot at>]

Is anybody aware of any cygwin app (supported or not) which uses/needs 
the sync() system call?
I found some occasional encounters of fsync(), but luckily no sync() 
yet. only in some unused testsuites :)

sync() should flush all open or cached file data and metadata. and 
volume master blocks.

The problem is that I have a simple patch, but this might get tricky if 
there are more processes involved, which I doubt. I doubt that there 
such a thing exists and that it will be useful at all.
We could also just flush all local NTFS volumes, but this would need 
Administrator privileges (and therefore probably cygserver support).
