Yes, `split-width-threshold' might help in these situations.
But I think its default value should not be such large value as
`split-height-threshold' has.  However, for the default behavior of
vertical splitting this large default value seems right.

This means there is a difference in semantics of `split-height-threshold'
and `split-width-threshold'.  IOW, they are NOT complete equivalents
rotated 90 degrees.
