I now tried the remaining backends on Mac OS X. With the Qt4Agg and WxAgg backends, show() can be called repeatedly and blocks each time. The FltkAgg backend shows the same behavior as Tkagg. The implementation of show() in the FltkAgg backend uses the same _needmain as TkAgg. If I remove the _needmain stuff, then show() can be called multiple times with FltkAgg, blocking each time.
