Except this time is does not. If there is background processses on the 
tty, the client can either close the session and lose data or wait 
indefinetely for data from the background processes.

It needs server modifications that data from the pty session process 
leaders is not lost. I think rlogin and all other pty using programs have 
allready implemented this properly; which is that the pty buffer is 
first emptied and the connection is closed _after_ that.
