** Description changed:

  Final output generated after read from stdin is lost by empty if command
  exits quickly after the read.
  
  All output comes through fine if:
  -there is a lot of output after the read
  -command waits for a small time after the read (no matter if waiting before 
or after the final output though)
- -there is no read from stdin
+ -command does not read from stdin
  
  Example scripts attached.
  
  Commands:
  empty -f -i in -o out ./script.sh
  cat <out
  echo Test >in
