I'm hardly an expert, but AFAIK CPython's start-up issues are more due to a mix of architectural issues and the fact that it's hard to optimize imports while maintaining backwards compatibility with Python's dynamism.

Nobody in the project is seriously talking about a complete rewrite in Rust. Contributors to the project have varying opinions on how aggressively Rust should be utilized. People who contribute to the C code, low-level primitives (like storage, deltas, etc), and those who care about performance tend to want more Rust. One thing we almost universally agree on is that we want to rewrite all of Mercurial's C code in Rust. I anticipate that figuring out the balance between Rust and Python in Mercurial will be an ongoing conversation/process for the next few years. Have you considered simply rewriting CPython in Rust? And yes, the 4th word in that question was intended to produce peals of shocked laughter. But why Rust? Why not Go? http://esr.ibiblio.org/?p=7724
