Summary: very pregnant pause when opening notation view

Initial Comment:
It's a ludicrously simple composition with three empty segments, 
each only five bars long.  Opening a notation view takes on the 
order of seconds, during which time the main window gets that "I'm 
about to crash" look where it doesn't bother to repaint itself in a 
timely fashion.  I get a little CPU utilization spike too.  It's chewing 
through a whole lot of something, and I can't imagine what. 
 
The length of the pause seems variable.  It may be that the most 
egregious examples are when I happen to try to do this at the same 
moment autosave is kicking in.  The extremely long pause that 
prompted this bug report hasn't been repeated after several repeat 
performances, but there has always been what seems a 
disproportionately long pause; even when only opening a single 
segment.
