Progresss while executing AppleScript

Not that I've been able to find. Even the syntax:

send "theHandlerName" to this stack in 1 millisecond

doesn't stop the AppleScript blocking the whole app.

The only workaround I can think of is to have a second "helper app"  
with no GUI which you use to handle all the AS functions in the  
background, but this gets a bit over-complex.
