it's only unmounted after a timeout. so for example if I simply copy a
bunch of files to a flash drive, it will not umount after the copy
completes. for one thing the data may not get written because it's
sitting in io buffers.
you can't just yank the flash drive until the buffer is flushed.
so the best thing to do, I think, is to umount and wait for the
flashing light to stop, or busy wheel to go away, etc..
using the flush option for the mount command helps a lot.
