The attached patch adds atomic window support with a new customization
option, `gnus-use-atomic-windows', defaulting to nil. If t, a
multi-window Gnus layout will be treated as a single window when other
code pops up buffers. Ie, your completions buffer won't end up squished
between the summary and article buffers.

I'm pretty sure I've done the elisp manual cross reference incorrectly.

Thanks,
Eric
