This is "normal" because the lua 5.1 garbage collector runs whenever
it thinks there's enough memory used. The problem is that lua doesn't
know the size of the objects being created so it counts all user data
as just void*. At least this is my understanding of the situation. The
threshold can be turned down, but there will always be a huge
difference between the size of void* and any reasonable class instance
so you'd have to basicly have the gc running every cycle to keep up
which would slow things down quite a bit.
