The problem is in the core path handling routine, which evaluates paths from tail to head component rather than vice versa, as required by POSIX. The original authors probably implemented it this way for speed, and the drawbacks (as above) were only found much later. Why did we never changed that? Because the core path handling routines are long-winded, complicated, and probably the most crucial part of the DLL. Nobody dared to rip it apart yet, but that's what would be required. I'm sorry if that doesn't help you, but that's as it is right now, unfortunately.
