One pattern to address this was proposed by Randal Schwartz in 1997:
http://www.stonehenge.com/merlyn/WebTechniques/col20.html

Simplified:

Fork the long running process into the background. This process
can report its status to a file as it goes.

The page that the user sees can refresh it periodically, checking the status
via the file and reporting back to the user.

I've used this kind of pattern successfully myself.
