Noticed this in the PHP docs:

"Note: The set_time_limit() function and the configuration directive
max_execution_time only 
affect the execution time of the script itself. Any time spent on
activity that happens outside 
the execution of the script such as system calls using system(), the
sleep() function, database 
queries, etc. is not included when determining the maximum time that the
script has been 
running."

I suspect that the problem is because of the script getting stuck in a
state that the 
max_execution_time doesn't count towards.  
I am guessing this is because asterisk holds the connection open to AGI
forever and 
relies on the AGI script to end of its own accord.
This isnt necessarily a bad thing as you may wish to keep processing a
script after a 
caller has hung up.

I think all you can do is add some timeout mechanism to the "waiting for
more dtmf" 
part and exit the script after so many seconds/minutes of no DTMF.
