Threads and the JAVA VM
================================================================================
For a quick tour on how Linux native threads interoperate with the JAVA VM, take
a look here: http://developer.android.com/guide/practices/jni.html
If you want to use threads in your SDL app, it's strongly recommended that you
do so by creating them using SDL functions. This way, the required attach/detach
handling is managed by SDL automagically. If you have threads created by other
means and they make calls to SDL functions, make sure that you call
Android_JNI_SetupThread before doing anything else otherwise SDL will attach
your thread automatically anyway (when you make an SDL call), but it'll never
detach it.
