The 'beforeunload' and 'unload' events are described in algorithsm here:
If you click the "prompt to unload the document" and "unload a document"
bits you'll get links to the algorithsm that use them. In particular, the
Step 3 is the one that prevents a browsing context from being navigated
while 'unload' is running.
Step 8 is the one that runs 'beforeunload'.
Step 17 references algorithms that each later reference the "update the
session history with the new page" algorithm:
Step 1 of that algorithm invokes 'unload'.
Sorry for linking to complete.html; the multipage copy is currently
undergoing maintenance as I write this. If you replace "complete.html"
with "multipage/" then you will get redirected to the multipage version.
