I should probably also add that this is close to impossible to
implement on JRuby (and I assume on IronRuby too, and maybe some
others). In case of JRuby, we build once and then the resulting
product can be used on various platforms, so those platform specific
things are queried at runtime. In some cases we just invoke a native
functions via FFI at runtime and only then would see
NotImplementedError out of those calls. So, basically, untill the
method is executed, we can't really know whether it is supported or
not on some platforms.

So, this new behavior is not "portable" in a sense that it won't work
on all 1.9.2-compatible implementations, which would only add to
confusion.

Thanks,
