It works fine also.

Synchronization is an additional feature, not basic thread support. It can
also be in a console app, but afaik then the application must be event
driven (return regularly to some main loop). Like e.g. the textmode IDE
(though it does not _USE_ threading)

In such mainloop checksynchronize should be called.
