[issue6717] Some problem with recursion handling

That's where 3.x is different: 3.x temporarily bumps up the recursion
limit a bit when it is first reached, in order to let various cleanup
handlers run as intended. This is a nice thing in the general case, but
means it can degenerate in more involved or desperate cases.

(although here it's not clear to me why a second recursion error occurs
after the first one)
