Deep coroutine recursion is not caught. This is a known problem:

http://lua-users.org/lists/lua-l/2005-09/msg00457.html

Unfortunately there is no good solution:

http://lua-users.org/lists/lua-l/2005-04/msg00069.html
http://lua-users.org/lists/lua-l/2005-04/msg00084.html

Corollary #1: don't do it. :-)
Corollary #2: don't give untrusted scripts access to the pure
              coroutine functions.

Bye,
