  Log:
  If the parent process has the trap bit set (i.e. a debugger had single
  stepped the process to the system call), we need to clear the trap flag
  from the new frame unless the debugger had set PF_FORK on the parent.
  Otherwise, the child will receive a (likely unexpected) SIGTRAP when it
  executes the first instruction after returning to userland.
