All other user agents don't clear event listeners. See  
http://tc.labs.opera.com/apis/XMLHttpRequest/onreadystatechange/002.htm  
for a testcase. As such, I don't think the specification would need to  
state anything in addition as it already describes the behavior  
implementations should exhibit.
