+ * last parameter in the trace_even and trace_interval_entry call is
+ * the stack level to report the PC in the trace record. so 0 means
+ * the PC of the current frame, 1 means the PC of the caller, etc.
+ * there's a dilemma here - these macros are included in the inline
+ * _mutex calls which get called from the (created during build)
+ * mutex functions in the mutex .c files. in that case, the level
+ * should be 1 - we don't want the PC of where in the mutex function
+ * the trace call is happening, we want the PC of whomever is calling
+ * the mutex function.
+ *
+ * but.. an app can call the inline functions - it can #include the
+ * appropriate libsync mutex .h files, and call the inlined _mutex
+ * function in their code. in that case, the appropriate level for the
+ * trace calls would be 0 - the user would want to know where in their
+ * code the call to the _mutex function is.
+ *
+ * so, we'll assume _LEVEL of 0 which is what the inline funtions need.
+ * when we build the files for libsync, we'll do a -D_LEVEL=1
