[Bug 21074] Need ability to load scripts without blocking onload

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21074

--- Comment #3 from Philip Tellis <philip.tellis@gmail.com> ---
The timeout has a use case, but I don't think it is a replacement for
nonblocking.

for example, you may not want to abort the download.  you might still want to
let it load up whenever it does.

Consider a server that generally responds in 50ms, but in 1% of cases takes
more than 5 seconds to respond.  The user will most likely still be on your
page 5 seconds after it starts loading, so the script load will complete, and
can still do what it needs to (eg: stats gathering, or a widget at the bottom
of the page).

Blocking onload for 2 seconds is also not acceptable because we may be blocking
execution of scripts for something that really does not care about the onload
event.
