Not quite: IIRC you've said that before, and I thought I corrected you
when you said it before.  ARM says for code which is modified and then
executed without proper synchronization:

  "Concurrent modification and execution of instructions can lead to
  the resulting instruction performing any behavior that can be
  achieved by executing any sequence of instructions that can be
  executed from the same Exception level, except where the instruction
  before modification and the instruction after modification is a B,
  BL, NOP, BRK, SVC, HVC, or SMC instruction."

Granted, this isn't quite nasal daemons, but "any sequence of
instructions" is pretty close.
