Yes.
What probably happens is :
- a request comes in for / (or /x..)
- it gets caught by the redirect rule, and a 302 (moved) response is 
sent back to the browser, indicating a new address of
http://hudson.warpspeed.com.au/hudson/  (or ../hudson/x..)
- the browser immediately and transparently sends back a request for
/hudson/
- this request is caught by the same redirect rule, results in a new 302 
(moved) response, with an address this time of
http://hudson.warpspeed.com.au/hudson/hudson/
- and so on for ever

It would not matter if the server to which your redirect sends the 
request was not the same as this one.  But since here it is the same, 
you loop infinitely.

So either you find a way to tell your RedirectMatch that this applies to 
everything *except* URLs that already have "/hudson" in them, or else 
you use mod_rewrite in the way I indicated before.
