In practice I've noticed that we actually wait for twice the
echo_interval value to reconnect (/me has been doing a lot of
reconnection tests lately).

Great analysis! I remember reading through your blog some time ago but
forgot about this post. (Btw it would be even nicer if the code was
formated [1] ;)

Thanks,

I've used hilite.me to generate the html for the code and changed the
blog design. Hopefully will make it easier to follow. 

I still need to change my code walk through of smb3 encryption.
