 > Given how long it takes to build Qt, it might be worth combining the
 update to 4.5.3 with #21960

 Don't be such a pessimist. Personally, I always compile `qt4-mac` at
 night, and use the heat coming off of my laptop to keep the house warm.
 One compile is good for the whole night. Winter is slowly coming upon us
 in my neck of the world (Canada), so a few extra Qt compiles and I can
 sell surplus heat to my neighbours... ;-)

 Yes, definitely a good idea to merge the updates - thanks for the heads-
 up.
