Most frustrating.

Markus, what do you recommend? On Linux (and other systems) background 
processes will hold their fd 0,1,2 open and sshd will get get stuck in 
serverloop{2}. 

There is a hack in the portable version for SSH1 which breaks out of 
serverloop after a SIGCHLD and one pass through the 
wait_until_can_do_something() select. I have tried a hack for SSH2 
which breaks out of serverloop2 if a SIGCHLD has been received and
there are no active sessions left, but this causes the above problem 
with scp over ssh2.

Can you recommend a better approach?
