@kg as discussed please

• update the log message to contain value of the new opcode and the value of existing opcode after failed cmpxchg
  • so that we learn why it failed, why the racing opcodes are not the same value in the first place
  • if they are same, we should not produce the warning, because that's ok
• update the comment about threading doesn't work
• consider renaming "monitor point"

This appears to be fixed
