jvm thread Maps-To(isn’t)native thread: %%speculation

I don’t (need to) know HOW a jvm thread maps to a native thread. I believe by construction, JVM attaches house-keeping info on the native thread handle (something based on a ptr). The housekeeping data probably provides essential management features, such as

* thread dump
* interactive debugger support
* jGC knows all the live objects on a thread’s call stack
