Single instance applications on Windows NT/XP use the named mutex
pattern[1], to which we can provide a nice wrapper using GUnique I
think.

I think we can use a platform-based approach:

  * D-Bus, Xlibs and bacon on *nix on a soft dependency basis;
  * bacon on OS X;
  * named mutex and bacon on win32.

since GTK+ HEAD dropped support for 9x/ME, if GUnique is slated to be
integrated into GTK+ I think we can safely assume that 9x/ME are an
unsupported platform.
