The mount tables are only used to translate file paths.  Unlike Unix,
there is no locking mechanism that would prevent you from unmounting
a mount while you're in that directory.  In the absense of mounts,
it probably maps the current drive as-is (so "/" is the root of
whatever drive you're on).  Note that changing the mount table
while you're using that mount may lead to interesting results,
like `pwd` changing out from under you.
