How are virtual threads parked in Project Loom, specifically in scenarios other than LockSupport.park()? I've noticed that LockSupport.park() is used in FutureTask and CompletableFuture, but what about situations involving I/O operations? I came across this code snippet (link: https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/aarch64/sharedRuntime_aarch64.cpp#L1174-L1226) involving continuation yield intrinsic, but I'm unclear about where this intrinsic fits into the picture, as I understand intrinsics are typically used for performance optimization. Additionally, I'm curious about ObjectMonitor, which use pthread_mutex with cond (link: https://github.com/openjdk/jdk/blob/f61499c73fe03e2e3680d7f58a84183364c5c5ac/src/hotspot/share/runtime/objectMonitor.cpp#L757), how does it work with virtual thread where pthread doesn't exist?
