Okay, it still doesn't work, but I made a mistake in my testing. It *does* work fine if I "print Location" to any other domain, even if the target domain is on the same server. What *doesn't* fix the problem is doing a "print Location" to another domain with an htaccess/Redirect back to the original domain, even if the target domain is on another server.
I tried doing a "print Location" to a .cgi file on another domain, that does a "print Location" right back to a page on the target domain, but that doesn't work either -- the browser still stalls.
I know the server isn't tied up because while [some long process] is executing, I can still load pages from that domain the script is on in another browser window.
