In addition to the resources already mentioned I believe that the current
ResourceLimitertrait is another avenue to limiting memory of modules, so I'm going to close this.

I wish to use wasmtime in a server to run small untrusted code blocks. I need to limit the maximum memory consumed by each running block to 5MB. I looked through the docs and found no way to restrict how much memory the VM can allocate. There seems to be a built-in limit of 4GB. See #1872 .
Let's support or document how to restrict memory usage.

For completeness, another suggestion cited here: https://users.rust-lang.org/t/how-to-set-max-memory-limit-in-wasm/64725/10
The flags can also be declared in a .cargo/config.toml file so that a regular
cargo build --target=wasm32-wasicommand can be used:[target.wasm32-wasi] rustflags = ["-Clink-args=--initial-memory=2621440 --max-memory=2621440"]
