Discussion
An application is considered multithreaded if a thread was ever detached from the main thread using either detachNewThreadSelector(_:toTarget:with:) or start(). If you detached a thread in your application using a non-Cocoa API, such as the POSIX or Multiprocessing Services APIs, this method could still return false. The detached thread does not have to be currently running for the application to be considered multithreaded—this method only indicates whether a single thread has been spawned.
