No. This problem is related to multi-threading in Lua. The point here is that,
when Lua calls a function (a Lua function), the interpreter calls itself
recursively. So, when you get a break-point there is a lot of C stack behind
you, not only Lua stack, and the only way to have a "suspend, continue, stop"
feature is having this in C, too. Some people have changed the interpreter to
avoid this recursive structure, but this is not a trivial task, and does not
work for all cases (for instance, "dostring" and "dofile" must call the
