provide versions of the functions that return on error, for those cases
where they are needed. And then have the "normal" function call this
function, and on failure, act as it acts now (i.e. exit)?
I realize that just blowing the process away on this type of failure is
a very reasonable thing to do, but in a very few cases here, we need to
recover and stumble along in the case of such failure, and try to at
least get to a sane state before dying.
