  99
 100    The return value is represented using the arrow "->>".  For simple
 101    functions, the arrow can be printed on the same line as the

 103    vertical line of the function.

 105    The first column contains the file name, the second the line
 106    number, and the third a number increasing for each trace line.
 107
 108    Note, when trace output from several threads are mixed, the output
 109    can become misaligned, as all threads (currently) share one state.
 110    This is post prominent when the EVENTS part is enabled.

 113    "cleanup" extension. */
