This is a small thing, but it feels like the right thing to do, especially since each instance of the uuid modules allocates a separate buffer for cached values.

The entropy pool is only used for UUID v4 (the crypto random one), while cls-rtracer uses UUID v1 (the node id + clock time one). But I don't mind upgrading this dependency.
