This lightweight_once is not a public component and is not a part of
Boost.FSM interface. No users will ever see it unless they dig into
the library implementation. And I had no intent to make it public
anyway - there is Boost.Thread implementation for that purpose. The
only reason why I implemented it is that I want my library to be
header-only. Therefore I don't see much sense in asking a separate
review for something that is an implementation detail of some another
library. The fact that I tried to make this detail general enough to
be able to be reused somewhere else (e.g. in another library) doesn't
mean that it is public.
