The streaming functionality works, to at least some degree. If it  
didn't, you'd be staring at a completely blank window much longer  
during status and (especially) updates.

ERb generates Ruby source code (replacing HTML with statements that  
append the HTML text to a string variable) from the RHTML file and  
then executes the source code to produce the final HTML. You just need  
to set up the ERb compiler class to publish the output to a stream  
instead of gathering the output into that variable. The code to do  
this is very small, but should be factored out of the format_status.rb  
into some utility file somewhere. It is strikingly non-obvious.
