Why Mongrel doesn’t cancel connection on error?

Example: (Mongrel using Rack)

…  
def call env  
begin  
p :start  
sleep 10  
ensure  
p :stop  
end  
end  
…

Open browser, go to localhost:8080, and immediatelly close the browser.  
Output will be:

start  
\<waits for 10 sec\>  
end

Why it doesn’t cancel/kill thread immediatelly?
