FAT's granularity is 2 seconds, but I think I saw rumours on the web
archives of various mailing lists that on some filesystems, operating
systems, virtual machines, etc. that the effective granularity of
mtimes is sometimes 3 or 4 seconds.
Still not knowing what we are actually talking about, I wonder if
"sleep 2" or "sleep 4" couldn't be replaced with something like
touch a_temp_file
while mtime(thefile) == mtime(a_temp_file):
sleep 0.2
touch a_temp_file
If that could be made to work, it would be more reliable and faster
than "sleep 2".
