My Opera does not, which was useful today when I had code to check
several Easter algorithms for 5700000 years, at about 2000 years per
second.

My IE6 would allow longer and longer intervals between successive
warnings, but my IE7 warns every 31000 years or so - tiresome.

It would be nice to have a list of whether/how that can be changed for
various browsers. Obviously it ought not (by default) to be possible to
do it be code, but it would be good for a programmer to be able to ask a
user to make the change.

It would also be nice if the warning box had a control to disable the
feature for the current action or page.

For Firefox you can change dom.max_script_run_time (defaults to 10
seconds) with about:config

I wrote a BASIC compiler and VM in Javascript (GPLed) once. To say it
was a big pain would be an understatement and performance ... suffered.

Does, however, make a nice test of UA's Javascript speed. ;)
