Or you can delay showing the dialog for half a second, during which you gather progress data and estimate for how long the dialog would be shown. If it's less than a couple of seconds, don't show it at all.

Yep, that's another way. You still need to give some kind of feedback though if the dialog isn't shown otherwise it'll get perceived as lag. Also, say you wait 0.5 seconds until the dialog has to be shown but the operation takes 0.51 seconds: once the dialog appears you should still probably have it displayed for a minimum amount of time otherwise it looks like a glitch.
After 0.5 seconds you should have a good enough estimate to know that the operation will take 0.51 seconds, in which case you don't show the dialog at all. Of course estimations are sometimes wrong, but it shouldn't be a problem if you flash a dialog for 0.01 seconds once in a thousand times.
