---------------------------------------------------------------
Messing around with sub-processes is a well know source of bugs. As such, if we
make this change there should be plenty of tests. I'd like to see at least the
following in the test suite:
date +%Y%m%d
echo `date +%Y%m%d`
for i in {0..5}; do echo $i;done
