tor Shark profiles



I ran Shark on the latest stable Tor client for Mac OS X, most recently
patched operating system, G4 processor. One of the tests was done when
tor was starting, the other when using it to browse. The reports are
attached, however Shark has a lot of things it doesn't put in the
reports. It recommends inlining for client_would_use_router,
smartlist_remove, and a few SSL functions.
