Not really. You can't change the environment of an already running
process that isn't yourself. Even if one were to go into the System
control panel and change the environment variables, any shortcut
launchers (as I often use) will themselves need to be relaunched to
take advantage of the updated environment variables. Certainly, there
must be a way to refresh the internal environment variable table based
on the current registry settings, but that would be based on a global
signal.

I'm not sure what the OP's post about thinking in "ant" is, because
Ant would be similarly limited. This is not a Ruby limitation; it is
one of the few limitations that is essentially cross-platform and
found on every platform in existence to the best of my knowledge. The
only reason that shell script functions and DOS/Winodws batch files
can affect the current level's environment variables is that they are
not in a separate process and are therefore just modifying the current
process's environment variables.
