Obviously, Rob did it.  He often edits the descriptions.  His description
is a bit less misleading, IMHO.  The lib doesn't really do much.  It's just
a way to see how long things have been going on since the last time you
checked.  If it's been long enough, the user makes a call to the GUI lib
to check for any events that have been queued up.  I might have summarized
it like this:

"A library to help keep track of how long a task has been working, so that 
you can check for user events to avoid blocking the GUI."

Not that it isn't useful, but it's not really threads at all, since threads
would imply some sort of scheduling mechanism, as noted by Rob.
