IO-Tty and Expect now correctly handle the controlling terminal of the 
spawned process, that is, the spawned process runs in its own process 
group and gets the slave pty set as its controlling terminal (otherwise 
Expect wouldn't be able to handle password prompts).

But this process group gets into the way of the shells job 
control. /bin/sh doesn't have job control, that's why the mentioned 
workaround works.  Another way would be to use the utility 'nohup' 
(don't know, which system it is available on, I have it here on AIX) 
for putting commands into the background.  It also handles the case 
that the background process would get a SIGHUP if the user logs out of 
the foregropund shell...

Hope this helps,

Roland
