Gentoo guest Freezes during compile

There appears to be a thread deadlock issue when using Gentoo guests to compile software. This issue only occurs if the virtual cpu's are increased past 1. It makes no difference if there are 2 or 8 cpus allocated to the guest. I am pretty sure this is not limited to Gentoo guests however it is very easy to reproduce using Gentoo.
Steps to reproduce: Setup a vm with more than 1 virtual cpu (more the merrier) Set make -j to something like the number of cpu's +1 Start compiling something large (emerge -v --emptytree world) and wait.
It usually goes though several packages before it locks up. The best I can tell this is a thread dead lock issue and not something like a kernel panic. I have attached the kernel config that I am using to duplicate the issue.
