Have we reached the point yet where we can just get rid of special /dev
handling entirely? Maybe we could just add /dev population to setup.exe
or even have cygwin1.dll itself run a program if it detects an unpopulated
/dev, sort of like how udev is handled in linux now.
My only reservation with doing things this way is that we'd be making
cygwin perform a disk lookup every time someone wanted to get to open
