  If the current thread 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. Otherwise, the new thread will
  receive a (likely unexpected) SIGTRAP when it executes the first
  instruction after returning to userland.
