When you say "pretty dangerous", are you referring to the danger of  
reaching the limit of slots willing to be served by the server, or  
something else?

I would say that any server that supports the idea of long lived  
connections faces this danger, I don't see why httpd (suitably and  
sensibly configured obviously, probably with an event mpm and a limit  
as to the number of slots we allow to be long lived) can't play too.
