Insane memory usage

Description
Running Win8/x64 limited to 2GB ram out of 8gb and 2 cpus (amd-v,np,nx) out of 4 on Win7/x64 I had huge jump in memory usage where committed heap increased to 13.5GB and system started swapping like crazy. This happened while installing Visual Studio 2011 beta.
Such usage persisted after VM suspend (which BTW took about an hour), reboot of host and resume. After fully restarting VM everything seems normal.
Inside attachment you will find three logs:
- first start of vm where vs2011 setup was executed adn vm suspended
- from resume to shutdown
- fresh start
and a virtual memory map for vmmap.exe utility from sysinternals.

Your attached vmmap file indeed looks like there is a memory leak. However, we were not able to reproduce this problem using your testcase (installing VS 2011). This problem could also be related to your graphics hardware or actually your graphics host drivers.
Do you have any chance to reproduce this with a VM where you can disable 3D support? Perhaps also with Windows 8, just without installing the Guest Additions and disable 3D support for that VM. It would be a great help if you (or anybody else) could do these tests. If you experience a similar memory usage with 3D disabled then the problem must be in another code path.
