notebook -- implement a way of parsing script tags in output as they appear (but none that already appeared) #2909
Description
The canonical example to get to work is the following (submitted by Jason Grout):
for i in range(5):
print html('<script>alert(%s)</script>'%i)
sleep(1)
would pop up a dialog box about every second.
This feature was requested by gerhard <ge01705@yahoo.de>.
