Matrix.new() returns a userdata object. Lua's gc threshold starts out

Lua may not be seeing that the memory usage by the Matrix is high, so
it doesnt see a need to GC. If I understand how the GC works, it will
keep track of the space taken by Lua objects and cycle when there is a
certain size limit. Since a userdata object is quite small in Lua, it
oughtta take quite a while before that limit is reached.
If you can manage to allocate the Matrix data inside the userdata,
then
Lua may have a better chance of seeing the rapid increase in space.
