[Dev-luatex] Too many tex.runtoks() calls overflows input stack

[David Chiang]

Greetings, the following code

for i = 1, 10000 do
  tex.runtoks(function () end)
end

causes the following error for me:

! TeX capacity exceeded, sorry [input stack size=10000].
<inserted text>
                BAD
<inserted text> BAD

<inserted text> BAD

<inserted text> BAD

<inserted text> BAD

<inserted text> BAD

...

Is this the intended behavior, and is there a way to pop from the stack to
avoid the overflow? Thank you very much!

David
