* All threads are Linux threads, scheduled by the kernel.
* They're usually started from managed code (using Thread.start), but they can also be created elsewhere and then
* attached to the JavaVM. For example, a thread started with pthread_create can be attached with the
* JNI AttachCurrentThread or AttachCurrentThreadAsDaemon functions. Until a thread is attached, it has no JNIEnv,
* and cannot make JNI calls.
* Attaching a natively-created thread causes a java.lang.Thread object to be constructed and added to the "main"
* ThreadGroup, making it visible to the debugger. Calling AttachCurrentThread on an already-attached thread
* is a no-op.
* Note: You can call this function any number of times for the same thread, there's no harm in it

/* From http://developer.android.com/guide/practices/jni.html
* Threads attached through JNI must call DetachCurrentThread before they exit. If coding this directly is awkward,
* in Android 2.0 (Eclair) and higher you can use pthread_key_create to define a destructor function that will be
* called before the thread exits, and call DetachCurrentThread from there. (Use that key with pthread_setspecific
* to store the JNIEnv in thread-local-storage; that way it'll be passed into your destructor as the argument.)
* Note: The destructor is not called unless the stored value is != NULL
* Note: You can call this function any number of times for the same thread, there's no harm in it
* (except for some lost CPU cycles)
