Hello Bogdan,

there is small misunderstanding going here. When I asked if the assert(0)
in free is really needed, I meant something like `is this situation really
that critical that we should assert because of invalid invariant here'?
The reason is that sometime I found my own code to be too restrictive and
so some asserts might be removed during the later development phases,
hence I asked if this assert is not just relict from the history which
might be removed.
