SO, in our cases there are 2 options:


1) add line 
	{ echo QUIT > /dev/tcp/127.0.0.1/25025; } 2>/dev/null
  before 
	wait ${smtp_dummy_pid}

in test-lib.sh


2) add line
	kill ${smtp_dummy_pid}
  before 
	wait ${smtp_dummy_pid}

in test-lib.sh *and* add that fflush (output) before free (line) in 
smtp-dummy.c function receive_data_to_file.

folks! opinions!
