the above wasn't tried, b/c it would be a pain in the ass to get the
code out of an email. send it as an attachment in the future.

there are other things that are kinda messy about the code, that i
haven't touched, but this should work. returning false from the
pbar_update function when called from the timeout closure will uninstall
it. calling it yourself and returning false will do nothing.
