Why are my reference counts never reaching to 0(ZERO)

[Gustavo 'Gus' Carreno]

Hey Y'All,

Coming back with a new problem now: Interfaces, and references not reaching 0(ZERO).

My intention is to have a TInterfacedThread, much like the TInterfacedObject.
I created the class, the respective Interface and the QueryInterface, _AddRef, _Release methods required to do the Reference count.

I now need help to assess why my references on IManagerThread and IWorkerThread are not getting to 0, subsequently not calling the destructor and leaking memory like a sieve  :'(

The project is hosted on GitHub and you can get the source here.

Any help will be very appreciated since I'm at the stage pulling my hairs

Cheers,
Gus
