/**
 *  Test to ensure that the execute mechanism works fine on *nix-like systems.  For these OSs we
 *  can effectively guarantee the existance of some programs that we can run.  Assume the search
 *  path is partway reasonable so we can access sh and echo.
 *
 *  <p>These test are a bit trivial but at least they are here :-)
