rust-lang/rust#115746 was landed on the rust-lang/rust side and added TIDs to panic messages, but that shim isn't implemented on Android yet. We test Android on this repo but not on rust-lang/rust so it's holding up the sync.
Initially I was going to just patch this up, but I think maybe cribbing from the Linux shim implementation is easy enough that I'll just add the required support on Android.
