It's not "fortunate", it's designed that way.  Redisplay is the lowest
level of the display code, and tightly bound to the event loop.  If
there's an X display involved, life is very difficult, because X
protocol is totally asynchronous.

But most things (like adding a tab widget) should be able to work with
higher level display features.
