+ * Like MozStackWalk, but walks the stack for another thread.
+ * Call aCallback for each stack frame on the current thread, from
+ * the caller of MozStackWalk to main (or above).
+ *
+ * @param aCallback    Same as for MozStackWalk().
+ * @param aMaxFrames   Same as for MozStackWalk().
+ * @param aClosure     Same as for MozStackWalk().
+ * @param aThread      The handle of the thread whose stack is to be walked.
+ *                     If 0, walks the current thread.
+ * @param aContext     A CONTEXT, presumably obtained with GetThreadContext()
+ *                     after suspending the thread with SuspendThread(). If
+ *                     null, the CONTEXT will be re-obtained.
