N2178 has the same outlook but recommends considerably more cancellation points (the entire posix set if I understand correctly).
N2178 doesn't recommend a specific set of cancelation points. I expect that the standard would need to define a list of mandatory C++ cancelation points (potentially covering more than just the threading portion) and a list of optional cancelation points (which would be similar to the POSIX list of optional cancelation points with a few subtractions such as fclose.)
Thanks for the clarification. If it helps (the readers) here's a link to the posix cancellation points (and optional points): http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html#t... The rationale for my conclusion about N2178 was that once we hand control over to pthread_cancel, we're pretty much in the hands of the posix committee (or at least the posix implementors). We may be able to make some agreements with them. -Howard
