what happened was probably that the GC didn't see any need to collect.

Lua only keeps track of the memory used inside Lua.  if your userdata
holds only a pointer, or a small structure with references to bigger
objects, that would be the only size that Lua knows about.

to get better results either put most of your object's data inside the
userdata, or add some close() method that releases any resource
external to Lua.
