DropPrivileges() is used in exception_port_tool, so that when it is installed as a setuid executable, it only uses elevated privileges to obtain a task port for its -p option, and then relinquishes those privileges. It is difficult to provide a test for this function, because it must be running setuid or setgid in order to do anything interesting. However, the function contains its own CHECKs to verify that it behaves properly. R=rsesek@chromium.org Review URL: https://codereview.chromium.org/727053002
