I've merged today's svn trunk into the git branch dmalcolm/jit, pushing it as 81d39bf76e3ffd4e62c307cc8d22df18572eec19
Specifically, this is from trunk r215958 aka e012cdc775868e9922f5fef9068a764546876d93 bringing in all changes since 215803 aka 68874c5d021dd6b8b740ffd23960e46e333270b5 (2014-10-02) [am continuing to experiment with embedding the driver in-process within the jit library, and wanted r215861 as part of that]
