1) It has a bug which is already fixed in the main trunk
  2) Its code was already committed to the main trunk

1e71c9e56e Merged patch-unallowed-lock-cases patch. 
According to the Intel manuals:

  The  LOCK  prefix  can be prepended only to the following instructions
  and  only  to  those  forms  of the instructions where the destination
  operand  is  a  memory operand: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG,
  CMPXCH8B,  DEC,  INC,  NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG. If
  the  LOCK prefix is used with one of these instructions and the source
  operand  is a memory operand, an undefined opcode exception (#UD) will
  be  generated. An undefined opcode exception will also be generated if
  the  LOCK  prefix  is used with any instruction not in the above list.

 Checking of the LOCK prefix done in fetchDecode state and not overloads
 Bochs's execution.
