The changes are good. Now replace references to chapters/compute/.../drills/tasks/.../ to references to the archive and add a lab6.md file that tells students to download the archive from the lab-archives branch. Follow the model from this PR #169.

| The GIL also makes it so that individual Python instructions are atomic. | ||
| Run the code in `chapters/compute/synchronization/drills/tasks/race-condition/support/python/race_condition.py`. | ||
| Every time, `var` will be 0 because the GIL doesn't allow the two threads to run in parallel and reach the critical section at the same time. | ||
| This means that the instructions `var += 1` and `var -= 1` become atomic. | ||
| After implementing them, run each version using 1, 2, 4, and 8 workers for both threads and processes and compare their execution times. | ||

| If you're having difficulties solving this exercise, go through [this](../../../guides/sum-array-threads.md) reading material. |

This part has been removed because it referenced an exercise from Lab 8. Keeping the lab materials separate will be less chaotic for students.
