 // returns.
+//
+// Critical native functions are a shorthand for the use of
+// GetPrimtiveArrayCritical and disallow the use of any other JNI
+// functions.  The wrapper is expected to unpack the arguments before
+// passing them to the callee and perform checks before and after the
+// native call to ensure that they GC_locker
+// lock_critical/unlock_critical semantics are followed.  Some other
+// parts of JNI setup are skipped like the tear down of the JNI handle
+// block and the check for pending exceptions it's impossible for them
+// to be thrown.
+//
+// They are roughly structured like this:
+//    if (GC_locker::needs_gc())
+//      SharedRuntime::block_for_jni_critical();
+//    tranistion to thread_in_native
+//    unpack arrray arguments and call native entry point
+//    check for safepoint in progress
+//    check if any thread suspend flags are set
+//      call into JVM and possible unlock the JNI critical
+//      if a GC was suppressed while in the critical native.
+//    transition back to thread_in_Java
+//    return to caller
