Today i noticed that this property was returning a value of 4, when i only have 2 cores. This is no big deal. I just thought i would mention it to someone because i couldnt find a similar issue submitted here in a search. CPU: AMD Athlon II x2 215 OS: Windows 7 Ultimate sp1 x64

Unless you can provide us with some debug data for this function, nobody can debug this unless they have the exact same or similar CPU, which I certainly don't have.

Confirmed, returning 16 for me(fx 8350).

Returns 16 for me with FX-8350 on Linux 4.0 x86-64 Appears to be an AMD issue.

Appears to be a phobos issue because other tools display normal count.
