  22 /* Solaris x86 2.6 and 2.7 targets have a kernel bug when stepping
  23    over an instruction that causes a page fault without triggering
  24    a hardware watchpoint. The kernel properly notices that it shouldn't
  25    stop, because the hardware watchpoint is not triggered, but it forgets
  26    the step request and continues the program normally.
  27    Work around the problem by removing hardware watchpoints if a step is
  28    requested, GDB will check for a hardware watchpoint trigger after the
  29    step anyway.  */
