Yes, this problem has already been reported, but should
be solvable by expecting 'eof', which is activated
when the child exits, so this is probably your best bet.  

Expect does not handle SIGCHILD (which it should; I intend a 
complete rewrite and have this on the feature list) but 
instead relies on EOF detection from the pty.  But as the 
state machine is heavily patched, there might be some problems 
with that also.

I'm already investigating this, but I guess this is best solved
by a clean redesign, so it will take some time.

Thanks for telling.
