Semaphore.WaitForSignal under Canvas.BuildBatch causes a slow editor in Play mode
Steps to reproduce:
1. Open the attached project "Temp Project" from the ownCloud link
2. Open "Main Scene"
3. Turn on the Profiler window
4. Enter Play mode
5. Notice the Spikes from Semaphore.WaitForSignal
Expected results: Semaphore.WaitForSignal does not cause spikes in the Profiler window and making Editor slow
Actual results: Semaphore.WaitForSignal causes spikes in the Profiler window and makes Editor slow
Reproducible with: 2019.2.3f1, 2019.3.0b1, 2020.1.0a1
Note: 2019.1 breaks the project and its packages
