toywasm_repl_invoke: wait for other threads in case of non-trap return

yamt · yamt · commit c56859523e77 · 2022-12-20T21:12:48.000+09:00
Note: for some reasons, the current logic in wasi-libc crt returns without wasi_proc_exit when the exit code is 0. maybe just to save a host call? cf. WebAssembly/wasi-libc#367
