servicepack v1.2.16 — service-manager tests stop synchronizing on sleep Test files only; no framework behaviour changed. TestServiceManager_Stop and TestServiceManager_Run each used a time.Sleep in place of the condition they actually depended on, and both were load-bearing -- zeroing either fails the test. Under load they failed for reasons unrelated to the code under test, surfacing as an unexplained flake in a consumer's CI. Both now wait on the real condition. Consumers inherit the fix on their next servicepack-update.
