That's not how it works internally in Lua 5.1 anymore.
Have a look at markroot() in lgc.c. Nowhere does it mark L,
the running thread (that called luaC_step).

atomic(), line 539:
  markobject(g, L);  /* mark running thread */

The comment leads me to believe that the intention is to mark the running thread, which would seem logical.
