I've added a new command 

  OptimizeMesh "algorithm";

in the parser (SVN rev 22185), so you can now simply add something like

  // ... your geometry ...
  Mesh 3;
  Optimize "Netgen";
  Optimize "Gmsh";

in your .geo file.

@Alexander - this might also allow you to fix your optimization problem, e.g. by running the two optimizers in sequence.
