Stack overflow issue after heavy-duty use

After roughly 10k requests (short lived, one after another) I've got this exception:

Can you provide a standalone example script that reproduces this?

It seems like this must be a language bug—as long as you're invoking http separately each time, there's no way it should be able to build a stack like that unless something unexpected is happening at the language level.
