Then don't set such a high history-limit?

Well, you could set history-limit before spawning new panes for certain
things.

Where are you seeing this? It isn't applied retroactively, and it's
specified at the point the window pane is created. When lines are added to
the grid, then the history-limit is used to work out which lines to free;
it's a rolling total if you like. When you hit the history-limit, lines are
removed to make way for new lines, but the limit then is always the
history-limit.

It's freed when the pane ends.
Really what ought to happen is that lines aren't preallocated based on the
history-limit, but the grids are realloc()d when needed. However, this
would not only mess with wrapping of lines in panes, but it would make it
slow.
