Is good support for self-modifying code a real  issue?  all  CPUs  support  a
"modify  code  -- invalidate all caches -- execute" cycle, which is enough to
run  (say)  loaders &  debuggers;  i  THINK  this  is  enough  for  all  real
applications, but want to be sure.

Are any exceptions to this (AI or other) known?
