This will fail to bootstrap unless #9257 lands first. |

Loosely related to this change: these actually allocate a new buffer, would it be possible for begin_unwind_ to be passed Rust strings and uints rather than C ones?

That would be a nice change actually, it seems fairly nicely separable from this change, however, so I think I'd attempt to do it in a later commit.

Could this become something like
let name = task.name.map(|s| s.as_slice()).unwrap_or("<unnamed>");
format_args!(|arg| { ... }, "...", name, msg, file, line);
This lifts various restrictions on the runtime, for example the character limit when logging a message. Right now the old debug!-style macros still involve allocating (because they use fmt! syntax), but the new debug2! macros don't involve allocating at all (unless the formatter for a type requires allocation.
