If you issue a script command, run a process with takes a little while and
then an exit command to close the script file and return to a command prompt.
viz:
cd /usr/pkgsrc
script /tmp/ll
cvs update -dP
exit
what happens is you don't get a command prompt - its like the script command
freezes and doesn't return. Issuing a ps shows the script processes:
The small patch below fixes it for me.
