You can, in one command, issue a number of resize requests.  I doubt we
want each of them cause a redisplay/redraw before the command completes.

The wrapping menubar problem is one of the w32 API - it's nothing we can
do about.  Personally, I considered Jason's reaction too drastic.  So
maybe we should make it conditional on the presence of a menubar.  Also,
I see other applications truncate the menubar in a similar situation.

Anyway - I don't have much of an idea what to do here.  If you can
provide any patches I'll be happy to test them.
