I'll see what's going on in my code, that the message isn't replied to.

But in general, this means that a buggy (or malicious) peer can, by  
withholding replies, cause my app to hang forever when closing the  
connection. I can't allow that (it's a DoS attack.) Could  
vortex_connection_close be modified to use some sort of timeout?
