But this code can also run be executed by other commands, such as git-read-tree and git-sparse-checkout, which are currently not tested with multiple workers. To promote a wider test coverage without duplicating tests: 1. Add the GIT_TEST_CHECKOUT_WORKERS environment variable, to optionally force parallel-checkout execution during the whole test suite. 2. Set this variable (with a value of 2) in the second test round of our linux-gcc CI job. This round runs `make test` again with some optional GIT_TEST_* variables enabled, so there is no additional overhead in exercising the parallel-checkout code here. Note that tests checking out less than two parallel-eligible entries will fall back to the sequential mode. Nevertheless, it's still a good exercise for the parallel-checkout framework as the fallback codepath also writes the queued entries using the parallel-checkout functions (only without spawning any worker).
