Simply doing 2 passes to know the size is dead simple actually, isn't it?

I have a high doubt that it's slow. Going from 0.1s to less than 0.2
doesn't make a noticeable difference.

Instead of offering arbitary settings, we could simply allocate the
space that is needed, accurately to maybe 1k. And of course one can
still run out of memory with your suggestion, especially if one has
chosen the (again, arbitary) setting wisely to be as accurate as
possible for the current theme.
