I seem to remember in the original thread (I am that old) that another poster identified this as a mistranslation of 'try, catch, finally' and the post overall was talking about throwing (vomiting) exceptions. I don't have a reference for that though sadly!
(edit: never mind, I see the original is linked there already. Please apologise for your stupidity!)
Well, there is a Google Groups link. But it doesn't include any speculation as to the meaning of the question. It contains no responses other than two requests to repost the question in Japanese.
Indeed, so I misremembered. I didn't come up with the try-catch-finally idea myself though so perhaps I'm thinking of an earlier showing of this from somewhere.
