Comment 12 for bug 713879

Just as a point of reference:
$ dpkg-query --show byobu
byobu 4.37-0ubuntu1

$ bhome=/home/smoser/t/byobu-home
$ mkdir -p $bhome
$ i=1; while :; do i=$(($i+1)); echo -n = $i =:; \
   HOME=$bhome sh -c "ulimit -n $i && exec byobu true" && break; done

What the above shows is that 'ulimit -n 15' worked. Anything less than that
was insufficient. The alternate 'HOME' was just to get default byobu configuration. By comparison, 'screen true' will run with 5.

Just information.
