Changes between Version 5 and Version 6 of Ticket #9659, comment 25

v5	v6
3	3	I'll try your workaround to set affinity of the '''host''' process (I'd have never thought it could help). Unfortunately I do a lot of multithread code and I'd like to test it in more real environment than a single-CPU one. After all, supporting multiple cores was one of reasons to move from Virtual PC to VirtualBox. Sad.

5		My guess is there is a bug in VirtualBox when switching thread context in guest OS under a rare condition (process is being debugged ?). I would appreciate a feedback from Oracle that would explain what (which VirtualBox component) can cause that and possibly to enable some detailed logging of the component etc.

7	5	Good news is that I've just got a reply in vbox-dev mailing list that confirms the issue https://www.virtualbox.org/pipermail/vbox-dev/2013-May/011456.html
