I recall checking in a previous discussion, and found some buffer-sizes
that should be made dependent on that.

It probably would be slower, though it might be interesting to massage
the code so that it could use plain malloc/free in GridText.c to see
how much faster the current scheme uses.

For the buffer sizes - there are probably some special cases that would
complicate things.
