+# binlog_start_pos is the postion of the the first event in the binary log
+# which follows the Format description event. Intended to reduce test suite
+# dependance on the Format description event length changes (e.g. in case
+# of adding new events). Evaluated as:
+#  
+#   binlog_start_pos = 4  /* binlog header */ +
+#                      (Format_description_log_event length)
+#
+#   Format_description_log_event length = 
+#                      19 /* event common header */ +
+#                      57 /* misc stuff in the Format description header */ +
+#                      number of events +
+#                      1 /* Checksum algorithm */ +
+#                      4 /* CRC32 length */
+# 
+# With current number of events = 171,
+#
+#   binlog_start_pos = 4 + 19 + 57 + 171 + 1 + 4 = 256.
