should be renamed to device_copy_n_async to make the non-blocking behavior more obvious.

The blocking three-argument version of device_copy_n should remain

When running the regression, the resulting logs seem to end up in third_party/tests/$TEST/.... This of course is not unnoticed by git, so a git status shows a ton of non-added new files added.

To reproduce:

make

git status   # observe all the files

Build or test artifacts should never clutter the rest of the code-base (we should regard them as read-only in
