Previous coverage lacked a scenario combining multi-process bind with VRAM oversubscription. This generates memory pressure with multi-process VM Bind activity and concurrent submission, exercising the bind pipeline under eviction pressure. v2: Removed helper APIs usage clock_nanosleep and commented code. v3: Refactored code to smaller functions. Added check for available SRAM usage and keep the max process to 20.
