IIRC the non-anonymous apr_shm code was for sharing data between threads
and processes. Moving this to \\Local\ on Win32 hides such flaws, but
doesn't serve to accomplish the goals of apr_shm, IMHO.
Can you offer a reason to support the \\Local\ shm space on win32? I'm
all for functionality, but not to simply pass failing test cases.
