Wasmer Freezes Up

Hi,

When I try in Wasmer I get no response:

@cemalgnlts ➜ /workspaces/codespaces-blank $ time wasmtime riscv-node.wasm

You need to pass --no-stdin to avoid blocking (e.g. wasmer out.wasm -- --no-stdin echo hello). AFAIK (as mentioned in https://github.com/ktock/container2wasm#wasi-runtimes-integration-status ), wasmer doesn't seem to support non-blocking stdin (i.e. select syscall on stdin) so this needs to be fixed for making stdio work on wasmer properly.

Yes, it works now, thanks.
