Try OS.Process.system "uname -s > tmpfile", which prints "Darwin" on OSX; I'm not sure what it prints under win/cygwin. Maybe worth splitting out "run a system command, pipe output to a temp file, and delete the temp file after returning a string", fixing issue #6 while we're at it.

I'm asking my Windows people what *OS.Process.system "uname -s"* does in their configurations.
