Dr. Memory fails to create symcache files from a process with an untrusted integrity level

_From [rnk@google.com](https://code.google.com/u/rnk@google.com/) on December 18, 2012 16:27:42_

Since April, Chrome's renderer uses the "untrusted" integrity level. The original diff introducing the usage of untrusted integrity: http://src.chromium.org/viewvc/chrome/trunk/src/content/common/sandbox_policy.cc?view=diff&r1=132476&r2=132477 Review URL: https://chromiumcodereview.appspot.com/9716027/ This manifests as message boxes from the renderer and gpu processes while running chrome tests. Looking at the code to set the integrity level, it looks like our logfile creation is probably also failing, and we may not be getting any memory checks on the renderer.
