Comment at: lib/xray/xray_x86_64.cc:116-121
   // Here we do the dance of replacing the tail call sled with a similar
   // sequence as the entry sled, but calls the exit sled instead, so we can
   // treat tail call exits as if they were normal exits.
   // FIXME: In the future we'd need to distinguish between non-tail exits and
   // tail exits for better information preservation.
Is this comment still correct?
