Heh... A Google search on that topic made for some interesting reading.
In light of it, I'm wondering at this curiosity, which I have not seen
with previous versions of cygwin1.dll:
$ ls -la /
[after 2-3 seconds delay...]
ls: reading directory /: No such file or directory

[Note: this is the same mount table I've been using for the past
several versions of the dll. So, does '/:' have something to do with
alternate data streams? Hmmm... Let's check with a streams-aware
enhanced command processor...]

This only shows up with 'ls [options] /' ie. when listing the Cygwin
root directory, and nowhere else. Any ideas?
