Deep Dive into Coroutines on JVM
summary
Explains how Kotlin compilers convert suspend functions into JVM methods that take an implicit Continuation and compile into a single state-machine switch that reuses one state object (far fewer allocations than callback CPS), shows generated bytecode and microbenchmarks (including creating ~100k coroutines cheaply), demonstrates integration via suspendCancellableCoroutine and adapters for CompletableFuture/Retrofit, describes thread control via continuation interceptor / coroutine context and cooperative cancellation with Job semantics.
