    Determine whether the given unix socket path is in a filesystem namespace.

    While most PF_UNIX sockets are entries in the filesystem, Linux 2.2 and
    above support PF_UNIX sockets in an "abstract namespace" that does not
    correspond to any path. This function returns C{True} if the given socket
    path is stored in the filesystem and C{False} if the path is in this
    abstract namespace.
