They allocate memory and advance current GC progress, but they won't
change the mode of GC.
My reply was about Roberto's suggestion to "forbid any GC operation while running
a finalizer"
If GC inside a finalizer is disabled, then simple operation "t.x=1" might raise OOM.
And it would be very difficult to find such a mistake in a Lua program.
You can not cover it with tests.
