Oh. A comment on StackOverlow says:
"The WaitForXxx functions accept parameters of the generic HANDLE type, which represents a handle to a kernel object. Condition variables are user-mode objects, not kernel objects, so you cannot use them with these functions, since they work only with kernel objects."

I only created this issue because of this comment in pycore_condvar.h:
---
/* non-emulated condition variables are provided for those that want
* to target Windows Vista. Modify this macro to enable them.
*/
#ifndef _PY_EMULATED_WIN_CV
#define _PY_EMULATED_WIN_CV 1 /* use emulated condition variables */
#endif
