split-height-threshold?

[Stefan Monnier]

What's up with split-height-threshold?
Has anybody ever used it?

It's compared to windw_height(window) and should thus be expressed in number
of lines, but its default value of 500 is then basically equivalent to
most-positive-fixnum.  I.e. "never split".  Was that really the intention?
I see no comment of it, and since this code dates back to revision 1.1,
there's no ChangeLog info either.
