Greetings. I have observed the same behavior (on win32).
Scripts that are invoked from the same browser through the same URL appear to bind to the same perl thread and are therefore serialized. Changing the URL appears to bind the request to a different thread. (My observation regarded access from a different <Location>: Udei's experience shows that a URL change suffices). I have often wondered wether this is incidental or specified behaviour. Cheers, alf
