NOT asynchronously

I think all this is result of big "gifts" from Apple.

How to explain you....

You have see that I have spend a lots time with this FSRef.
Apple have provide strange non-consistent logic for
    EXISTED and non-EXISTED objects.

To make it working I was need write special wrapper around,
Watch with help of some bool flags and so on.

I think REAL have fight with the same problems.

Probably they recognize that object already exists with some delay.
This is not because asynchronously.
I think just in their code exists few branches of calls.
And at least one branch do not check if object already exists.
And other branch do this, so RB start to see object exists.

This is only assumption.
If it is correct then small bug present in the RB code.
