I never even looked at the implementation of CheckSynchronize()... It was just given in another thread when I was working on the port from Delphi to Linux and thus from the Windows GUI environment to the non-GUI command line program environment.
The name 'Gui thread' is misleading. It's simply the main program thread. If you want to use TThread.Synchronize then the call to CheckSynchronize is needed. The LCL for GUI application simply calls it automatically for you. In a non-GUI command-line program, you're responsible for calling it from time to time.
