Changing this fixed the memory issues. Instead of creating one  
xmlhttprequest object and using it for the life of the application, I  
now create one when I need to make a request and destroy it after the  
response is handled. For some reason that I don't understand, my  
memory issues are gone and usage is steady for the life of the session.

Thanks!! (I'm not one for excessive use of puncuation, but felt like  
this deserved more than one exclamation point :-)
