> {{run_docker}} and {{launch_docker_container_as_user}} allocate their command arrays
using EXECUTOR_PATH_MAX, which is hardcoded to 4096 in configuration.h. Because of this, the
full docker command can only be 4096 characters. If it is longer, it will be truncated and
the command will fail with a parsing error. Because of the bind-mounting of volumes, the arguments
to the docker command can quickly get large. For example, I passed the 4096 limit with an
11 disk node.
