+1.

Further, primitive invocation is slow.  Try and provide a bulk primitive
that answers multiple attributes, especially if the attributes are obtained
from a single system call (as is the case with stat).

Further, try and come up with cross-platform abstractions so that a single
primitive can be used across platforms. One of the things that would
require a lot of thought is harmonising Unix symbolic links, Mac OS X
Aliases and Windows Aliases.
