Listening for interrupts

Some of GH's components seem to implement some sort of an interrupt listener (pressing escape will throw a blissful explosion icon) and the solution seems to have been cancelled. I've implemented some components that are doing some heavy lifting with often many iterations, that do not seem to take notice of these interrupts.

Is there functionality in GH that suports such kind of procedure:

while (doingheavystuff)
{
  if (Grasshopper.TheShitHitTheFan)
  {
    break;
  }
  // Solve the question to life universe and everything here    
}


Thanks!
