1. In a system comprising virtualization logic and a corresponding virtual machine (VM) running a first process, a method comprising: the virtualization logic maintaining an accessed minimum virtual address location corresponding to the first process running in the virtual machine; the virtualization logic maintaining an exit indicator for the corresponding first process indicating whether the first process is exiting, the exit indicator initially indicating that the first process is not exiting; the virtualization logic detecting that a page table entry corresponding to the accessed minimum virtual address location for the first process has changed from a valid status to an invalid status and, in response, the virtualization logic setting the exit indicator for the first process to indicate that the first process is exiting; and the virtualization logic, upon detecting a change in a first page table entry for the first process from a valid status to an invalid status, if the exit indicator for the first process indicates that the first process is exiting, deleting a trace on a page table page containing the first page table entry.
