//qc execution code.
//we have two conditions.
//one allows us to debug and trace through our code, the other doesn't.

//hopefully, the compiler will do a great job at optimising this code for us, where required.
//if it dosn't, then bum.

//the general overhead should be reduced significantly, and I would be supprised if it did run slower.

//run away loops are checked for ONLY on gotos and function calls. This might give a poorer check, but it will run faster overall.

//Appears to work fine.
