Let me try to understand it better. We start with the
fact that some parts of your code can be executed by
both boost and non-boost threads.

A stumbling block in my case is understanding how can
your code be executed by a non-boost thread unless, at
some level, you explicitly make it possible.

So, if I didn't completely miss the point, TLS cleanup
for non-boost threads is there to spare the programmer
from having to analyze complex scenarious and calling
sequences which may lead to a non-boost thread
visiting the 'unsuspecting' method on your object.
