"Well caught, SIr Davidson!!"

I tried a bit of a fudge test today "tailing" the said file fairly 
briskly while swapping some USB doodads and here at least, the change in 
mountstats was appearing quite some time after the USB had been mounted 
and the file manager appeared. Up to 2 seconds later. I don't know if 
that's an artifact or just a distro thing but it would seem that if that 
lag is widespread then polling and "stat"-ing it a fairly leisurely pace 
could suffice?
