If your application depends on it being set properly, then have the
application set it. This would just be a *default*, you could still
override it - and should if it's really that important to your
application.

Also, how many platforms can't we do this on? If we have BSD and
Windows covered already. on linux, I believe you can easily read it
out of /proc/self/cmdline, no?
