Sorry to jump into the middle of a good dialog with what might seem an
irrelevance, but how will these asynchronous exceptions (now being
re-thrown 'as sychronous') interact with exception specifications?

Badly is my only guess.

Not that this should interfere with finding a good model for
asynchronous exceptions or cancellations - far more useful to your
general user! But it might mean we put some more thought into cleaning
up exception specifications in C++0x, so that no problems arise.

Unless, of course, I am imagining a problem that does not exist - would
not be the first time.
