If I have a C module function where I want to be certain the Lua
garbage collector is not running temporarily for a particular piece of
code, I would use it then - just in case that function is ever called
from a context where the garbage collector has *already* been stopped,
and the calling function does not expect it to be restarted. In that
situation I would get the current state at the beginning, then
conditionally decide whether to start the GC again at the end.
