MRI currently expects the HOME environment variable to be set under Windows=
. Various operations involving ~ and Dir will fail if HOME is not defined.

However, HOME is rarely defined under Windows by default. Instead USERPROFI=
LE is what normally represents HOME. IronRuby is considering aliasing HOME =
to USERPROFILE if HOME isn't already defined at startup time.

Does this seem like something reasonable to do in our implementation?
