//! The `amem` binary's main thread gets eight megabytes of stack on Windows, as it has on
//! Linux and macOS. Windows gives a main thread one by default, and what `main` does
//! before the commands move to a thread of their own (src/main.rs) overflowed that in a
//! debug build: `amem init` and `amem doctor` both died with "thread 'main' has
//! overflowed its stack" on the Windows runner.
