@elizarov sorry to post here but I'm sure this could help a lot of other people.

I really struggle to understand how to properly cancel blocking IO calls since normal usage does not interrupt thread.

Goal would be convert some functions in a module to coroutines with blocking IO and some computation.

I get the isActive/yield and ways to cancel the computations, but not how to push the cancel to the blocking IO call.

If I understand correctly how to properly do the coroutines stuff it should be something like this

suspend fun x(): y {
   val result = withContext(IO) {
   do CPU computation checking for isActive()/yield

But from all that I read, cancelling the coroutine that call x() would still have to wait for the result to finish it's IO blocking call that only support thread interrupt)

Is there any usable documentation / sample that fully cover this need (for Android so without Guava if possible)

(Plan is not to use IO but an existing executor with asCoroutineDispatcher())
