Calibre and many CPU cores

Well I was hoping that until I ran Calibre v.0.7.49 on on my Intel i7 Core-720QM. Yes it has 4 cores and Hyper-Threading.

Actually it seems that there are 3 working threads (yes, there are 6 calibre-parallel.exe processes).

It should be at least 4 working threads (there are 4 cores). In the best situation there should be 8 working threads ( 4 cores multiply by HT). Just to not start another discussion - yes 8 threads are faster than 4 on this CPU - I tested it by Prime.

Can You tell me why it happened?
Thanks for your help.
