If a user looks at log_summary, finds VecVCLCopyTo, dumps that into a 
search engine, and can't find a PETSc function with that name, it 
certainly won't lead to excitement... But well, looks like it's still 
the better thing to do, as the whole host<->device communication issue 
needs to be prominently documented anyway.
