Well, yes, it's probably a bug if you want to think of es as a pure
lambda calculus, but it's a necessary consequence of using fork and the
environment on Unix.

Trying to shoehorn the semantics of the lambda calculus on top of Unix
may not have been the smartest idea I ever had.  This is one of the
places where it falls apart.
