[medusa] more uniform error handling in asyncore.dispatcher() ?

On second thought, I don't think this is a good idea: it throws
off the ability to exit correctly from a sequence of code:

def method (self): 
n = self.send (data)
[...other code...]

If handle_error() is called automatically from send(), then there's no
way for [...other code...] to know about the error condition so that
it might exit the method (or choose a different branch of an if,
etc...)
