I won't question the sincerity of your worry...for all I know
you might (or perhaps should) have shared it with the C++ 
committee.  

However, just to clarify my view:  I would expect try (sic) to
handle even synchronous exceptions either very locally or very
globally, with very constrained ambitions in the latter case
(which, of course, anything involving a signal handler would 
fall into).

I don't mean to disrespect the *extremely* hard work that has 
been put into some other programming idioms that place a lot of
value on exception safety of classes, etc., though I have some
doubts about whether those approaches can be adequately tested
and/or make it easy for programmers to be productive.
