To expand on that a bit, it's so Cygwin doesn't have to open and parse the
actual contents of every file it sees on a path to see if it's a symlink; it
only has to check those marked as system.  Since it's rare to find many files
marked system normally, this results in mega-savings speedwise.

Now if Microsoft would only get hip to this whole symlink thing....
