There are uses for the synchronous networking code, though I’m happy to be corrected. Two off the top of my head:
* Custom map tile APIs, Google etc., all seem to give you a synchronous callback to get image data. They’re going to call that in the background, so it’s sort of OK.
* Simple command line utilities. They’ve got nothing better to do than sit and wait.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
