That would be correct. The first parameter is just a unique token.
When you want to "raise the event," use the same token in wakeup().
wakeup() will wake up all sleepers using that ident. So if you have
multiple sleepers using the same ident and only want one to run, you
need to take extra steps to prevent races.
