I very much agree that error messages should first and foremost be helpful to our users. In this particular patch, we have two places where we emit this error. In `UtilityFunction::MakeFunctionCaller` I believe the current error is totally appropriate. That doesn't mean that I think it should be shown to the user as such. I didn't look at how this function is called, but if it trips, I would like to see an error along the lines of: error: Couldn't run utility function. Can't make a function caller while the process is stopped: the process must be stopped to allocate memory. On the other hand, in `UserExpression::Evaluate` I think it's totally appropriate to rephrase this, but at the same time I don't think we need to dumb this down. error: Unable to evaluate expression while the process is $STATE: the process must be stopped because the expression might requires allocating memory. I'll update the error messages accordingly.
