Thanks.  I'm running Emacs now with your patch and will inform you if
and when I find any problems.  But please be a bit less cryptic, at
least when talking to illiterate people like me ;-)

I suppose the -100 means to not handle "some" asynchronous resize
requests while the WM handles ours.  So

- if a maximize, iconify, restore group request is enqueued we'd drop
  most (or some) of it?

- if another asynchronous (not in the maximize, iconify, restore group)
  size-related request is enqueued, we'd honor it - "instead" of ours?

- if a non-size-related request is in the queue we'd honor it - even it
  has some of our code re-resize frames?

- if there's another frame we don't care about the
  record_asynch_buffer_change (); stuff?
