@nekoinemo Is there a way to have it block until it hits the first suspension, as

thread {}

appears to do?

That is not what

thread {}

does.

thread {}

works like

launch {}

.

And why would you want to do that? Seems like a weird thing to do

Ken, it's complicated :/

Btw, I'm adding feature into the next version of kotlinx.coroutines for some UI optimizations, but I am still curious about your usecase too.
