AsyncGPUReadback can leak memory under certain circumstances.
If you first read back into a native array, then do a normal readback, the normal readback can leak memory, if it reuses the request that was used by the native array.
Reproduction steps:
1. Create or open any unity Project
2. Add the attached C# script to the project
3. Add it to an object in a scene with just a camera
4. Enter Play Mode
5.a Monitor Memory usage in the Task manager or
5.b open Window/Analysis/Profiler and add the Memory Module
Expected: Memory usage rises up to a point and stabilizes there
Actual: Memory usage keeps rising
