We can do better than that heuristic. All of the POSIX systems I know
publish mtab by default. The mount utility by default will report the
types of filesystems.
While a path module should not depend on such information, I suppose,
there ought to be a way to ask for it.
Of course this is still an heuristic (at least some Mac filesystems
can be configured to be case sensitive rather than case-preserving,
and I don't think this information is available in mtab), but it's far
more accurate than using only the OS.
 Requires a system call or subprocess execution, and since mounts
can be dynamically changed, doing it once at module initialization is
not good enough.
