  16 # On GNU/Linux, a creating a thread bound to an unexisting cpu spawns
  17 # the clone child thread for a bit, which is then immediately
  18 # cancelled.  The spawned child may trigger a dlopen (for libgcc_s)
  19 # while being cancelled, which results in a trap being reported to
  20 # GDB, for a thread that libthread_db considers to be TD_THR_ZOMBIE.
  21 # Make sure we handle that scenario properly.
