Preventing program from suspension

I’m pretty new to Kotlin coroutines and I’ve faced a problem with calling an asynchronious function in main. The program below looks nice, except exitProcess call. Without it the JVM can’t exit.

package io.github.commandertvis.boredapi

import io.github.rybalkinsd.kohttp.dsl.async.httpGetAsync
import io.github.rybalkinsd.kohttp.ext.url
import java.net.URL
import kotlin.system.exitProcess

suspend fun main() {
    println(httpGetAsync { url(URL("http://www.boredapi.com/api/activity")) }
        .await()
        .use { it.body()!!.string() })

    exitProcess(0)
}

How can I improve this code?
