I'm no expert on this.  I just took a look at predicate
`window-splittable-p', and a first impression tells me
that you can set `window-size-fixed' to `t' in a given
buffer/mode to make it unsplittable.  But it apparently
applies to all windows showing the buffer, and I see no
way to apply that to a single window.

I see too (in (elisp) `Splitting Windows') that there is
window parameter `split-window', which it seems like
you can use to prevent a given window from being split.

Someone more familiar with this stuff will hopefully
chime in.
