I have done more testing using the SIV 4.01 [Test APIC] page.  The patch
improves things but when lots of SetProcessAffinityMask() calls are made the
the threads end up on the incorrect CPU.  It's possible I did not apply the
patch correctly, but I also applied
http://bugs.winehq.org/show_bug.cgi?id=19964 which did work, so I am fairly
sure it went in correctly.

To run the test download http://rh-software.com/downloads/siz.zip, run SIV.exe,
select the [Test APIC] page (Right/Click tray Icon or System
Menu->Machine->Test APIC) and then press [Start].  If that does not fail then
press [Swap CPU] and it soon will.
