[webkit-dev] DRT/WTR should clear the cache at the beginning of each test?

What "things" remain in the process across test runs that are visible to

As I've said before in this thread, it seems axiomatic to me that tests can
only be reasoned about if they run in a pristine environment.  This is why
we TestShell::resetTestController()<http://trac.webkit.org/browser/trunk/Tools/DumpRenderTree/chromium/TestShell.cpp#L300>;
so that a given test passes or fails the same way regardless of what other
tests have run in the same process earlier.  Given that we *do* reset the
execution environment between tests, it seems arbitrary (and unworkable) to
*not* reset the cache.
