This concept of "the browser"...

The situation being considered here is that you have two web pages in 
two different OS-level processes that have a MessageChannel between 
them.  One of the OS-level processes crashes (and hence obviously can't 
send any more messages, as you note).  The other one would like to know 
that its counterparty is gone.  How should it find out?  That's the 
problem I think Ehsan is trying to solve.
