For my education, do we always have to call _initialize_scm() on host objects?  I noticed that running layout tests always calls this, which runs svn and git to determine the checkout type, even though we never use the information (e.g., if all the tests pass).  It's slow on my Windows machine.

Nit: Capitalize 'this'.

Yes, this is well-covered by run_webkit_tests_integrationtest.py; will note that.

Will do.

You only need to call initialize_scm() if you need to actually access scm/checkout objects. We need this in the manager process in order to properly generate the json result information (although I thought Ojan had patched the code at some point to only do this during that routine). 

I don't think we need it at all in the child process ... this code was cloned from run_webkit_tests.py, and I will remove it. It is slow.

Will do.

When I run "new-run-webkit-tests --pixel --release svg" on the command line, I get:
