// General ConsoleWrite Threading Guideline:
// PCSX2 is a threaded environment and multiple threads can write to the console asynchronously.
// Individual calls to ConsoleWriter APIs will be written in atomic fashion, however "partial"
// logs may end up interrupted by logs on other threads. This is usually not a problem for
// WriteLn, but may be undesirable for typical uses of Write. In cases where you want to
// print multi-line blocks of uninterrupted logs, compound the entire log into a single large
// string and issue that to WriteLn.
