  Yep, it's a side effect of the way the virtual filesystem for /proc works.
If it ever mattered to anyone, it would most likely be a simple enough patch
to the cwd code in the cygwin dll to make it check the directory by trying
it out before it permitted cwd to succeed, but I don't know how much
performance impact it might conceivably have.
