Mistake fixed: Broken version of DDSLoader fixed
Mistake fixed: Broken version of DDSLoader fixed

On the timing_leak_fixes local branch I commited (and then merged that
branch to timing_instr...) a version of DDSLoader that used
Request_handler-->TheList()->execute_each() instead of
...->execute_current(). Fixed. So, now this code passes it's tests
again, and the leak I found in DDSLoader is patched.
