 This may or may not be a priority, but basic `tahoe` commands take a while
 to start. Profiling suggests this is just due to code imports.

 The ~400ms is from a i7-12700k, so a very fast CPU core. A large
 percentage of computers will be rather slower.

 For many use cases this is OK. If you're doing heavy scripting with `tahoe
 get' or something this will add up.

 Potential solutions are:

 * Something like PyOxidizer, which is designed to package up Python CLIs
 in ways that make them start faster.
 * Rewrite the CLI with a different, faster language?
