And limiting the recursion depth is quite reasonable: The python interpreter
doesn't perform tail call optimisation, each level of recursion depth eats
a bit more memory. Without a recursion limit a python process might hit
the memory restrictions of the OS kernel, which would cause the OS kernel
to just silently kill the interpreter process. Now image this happening
inside a mission critical server process ;)
