usize overflow in Vec::reserve

I’m using the hello-world example from the examples dir. This only happens with release builds, and it only happens after a number of successful requests (~12,000+):

thread '<unnamed>' panicked at 'Vec::reserve: `usize` overflow', /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/libcore/option.rs:332

Could you run again with RUST_BACKTRACE=1?

Perhaps fixed in 0.3.7?

I can’t repro on 0.3.7, so whatever the problem was it’s solved now.
