I can't reproduce this (but I only have an old Emacs 22 to hand to test).

I suppose that we use switch-to-buffer because it affects the buffer
list order, but I'm not sure; the reordering code is complicated and its
true goal is unclear. If we can use `set-buffer', we can just use
`with-current-buffer'.

A minor point: you can't restore point and mark in such a buffer, so
they would be lost at the next desktop-save.
