well, there's no way to make a range of bit patterns cease to exist -
that's even less feasible than willing the tide to go away.

nor, as I've said several times, do I advocate re-allocating that
range of bit patterns for any other purpose, or even declaring
that they must not be used.

it seems to me that the real question is whether we should continue 
to promote the idea that SLs are good for any kind of general-purpose 
use by applications (say for security), or whether we should discourage 
such use.  if we can discourage use of SLs except in isolated networks 
or other rare corner cases, we'll avoid most of the potential harm that 
can come from them.

indeed.  I actually think we might be getting somewhere.
