If there's not an existing Cygwin install, you don't really have to worry too
much about Cygwin processes running. ;^>

The docs all recommend killing all Cygwin processes *before* running setup, as
setup can not replace running exes and active dlls during the installation
phase, before postinstall rebase of replaced dlls.

If setup can not replace any exe or dll, it warns you have to restart your
system to complete the replacement. After the restart, you then have to rerun
setup with no Cygwin processes running to successfully rebase replaced dlls.
