Review comment:
Does it make more sense for the application _not_ to set a value when it
doesn't have a value? This seems like a weird quirk of an application's
configuration (environment variables) that makes more sense to address in the
application than in jclouds itself.
Also I believe that `System.getProperties().remove()` is thread-safe but can
mess up iteration order and anyway modifying global state is a bad idea.
