// Message output for the WebAssembly build.
//
// On wasm every log line written through stdio is an fprintf that reaches JS one
// character at a time (fiprintf -> vfiprintf -> __stdio_write -> _fd_write ->
// doWritev -> write -> put_char), and the browser captures a stack for each one.
// A runaway warning therefore does not merely fill the console, it makes DevTools
// unresponsive. This writes whole lines straight to console.* instead, and
// collapses consecutive identical messages syslog-style.
