	Patches much appreciated.

	And of course, getting some clean notifications of file-system state
allow us to do that, perhaps we need more.

	it is somewhat unusual for this to happen; however on Linux at least
'lsof' on the device / mount-point can tell you what processes are using
that file-system, which -should- be convert-able into some pretty user
display: "please save and close LibreOffice documents open on this
drive" (or whatever).

	I would suspect it is quicker and easier to add it in a more generic
way that would identify apps at the OS level; then you get it for ~free
for everything else too.
