I have a couple of "regular" places for doing this, one is a bus stop after cresting a reasonable climb (road drops a lot to go under a railway bridge), I get a good look at the road ahead, and if there is a steady stream of traffic then I'll pop into the bus stop and let vehicles past, else I'll signal the safe overtaking opportunity.
I encounter coaches frequently on one of the country road stretches - I'll often wave them by and stop pedalling to give them a way past - cars are fine, but it's much harder for coaches to overtake.
OTOH - Last night I was about to pull into a side road (roadworks so it's guaranteed clear) to let people overtake after a short hill. I hadn't been holding them up for more than 10-15 seconds, but they had appeared in quite a lump, and the next section of road is urban, narrow and uphill. But then one of them (not the one directly behind me) decided that vigorous use of the horn was in order, so I didn't bother.
