If you use DirectoryPlugin (http://minnow.cc.gatech.edu/squeak/2196) this
will be handled less incorrectly. Well, the #isAFileNamed: part of the
problem, anyhow. The issue is due to Squeak thinking that a unix directory
file is a "file".

I added some file stat primitives in DirectoryPlugin to permit a check
for this. Possibly some of this is generic enough to be moved into FilePlugin.
