 Not quite. Please leave that part there for now.

 Toplevel widgets don't really get show events that often and for the rest 
it's just few instructions.

 I don't think it'd show up in any profiling results, but since it's called 
only from Qt it should be easy to add it back if it's needed for some 
workaround again, so it should be ok. Assuming the startup notification code 
is really not needed anymore.
