It seems like an artifact left from the Ricochet frame implementation which could mess up the stack pointer, where as the new LambdaForms implementation shouldn't have that problem.

It’s not needed anymore.  The last time I talked to John about removing it he wanted to keep it for something else but I forgot what it was.  Maybe tail calls.
