passing env to child processes

[Keary Suska]

If I recall correctly, Perl should and does pass on it's environment,
because this can be a security issue with networked scripts. Depending on
your shell, you might have to "export" the environment for it to be
perpetuated through child processes, as long as you are using the shell to
invoke the subprocess. If you are bypassing the shell, I don't think you can
pass an environment. I.e., backticks and standard command pipes use the
shell, but system( $command, @params) does not, while system(
$command_n_parms) does.
