Constraints make the job of the minimizer more difficult. If the starting
configuration is bad enough that the EM step might be really useful, give
the potential energy surface a free run without constraints. And then in
such cases do a preliminary NVT with dt=0.0005 and no constraints to get
things relaxed further. Only once things are close to correct do you want
to think about constraints so you can increase the time step.
