I merge once a week, for this very reason.  So far, no conflicts,
since the changes are limited to the display engine, where no active
development happened for quite some time.

Also, all the changes for now have the form

  if (!bidi)
      old code
      new code

and changes only happen in the `else' branch.  This decreases the
probability of conflicts even more (and also avoids destabilizing the
stable code of yore).

Once the infrastructure part is over, and people start changing Lisp
packages, then yes, I guess the probability of conflict will soar.

And as I wrote, I also think the trunk should be Emacs 24, while 23.x
should be on a branch.
