and, of course, as soon as I sent my message, I could get in to the wiki
and update it.

All in all, that implementation was flawed.
I've got a new implementation that solves both of these problems, but
I can't seen to get in to the wiki to post it. The basic idea, though,
is to move the work from the server to the client. The client, running
the javascript, will wait for some amount of time and then call
ajax_response() on the server. The server will see if anything is
available for that client. If not, ajax_response() can return
immediately and wait for the next connection from a client. To avoid
any synchronization of client connections to the server, the wait
period on the client side is not constant (random between 3 and 8
seconds). Also, the server can send back what the timeout should be
until the next connection. This will allow the server control how
often the client connects (maybe depending on the page the user is
looking at).
In the short term, by adding a time.sleep(2) to the current
implementation of ajax_response(), you can avoid all CPU cycles being
consumed.

I just tried out the AjaxSuggest example servlet that was added to
Subversion last month. It works, but unfortunately it seems to
gobble up
100% of the CPU.
It looks to me like the problem is in the ajax_response method of
AjaxPage.
It uses an inefficient polling loop; instead, it needs to use a
threading.Event or Queue or something along those lines that it can
efficiently wait on.
