So it's not merely that FAT might not notice events within 2 seconds
of each other, but it actually loses precision (i.e., *can't* store)
timestamps too close to each other when copied from another file
system? I hadn't realized that.

By the way, have you done any experiments to confirm that this is the
cause of the slower status? It might also just be that the memory
stick is, you know, slower :-).
