Long circuit build times when connecting to onion services

This came up in shadow simulations, with a 10% network size, and some perf clients connection to onion services. Tor version is 0.4.7.3-alpha (git-a2971919ade15e07)

Here are a few examples. Lots more in the logs, but the process for pulling out the ones with long build times is currently a bit manual:
