memory leak in memMapIpc

[DualHappiness]

OS: Windows11 Platform: Visual Studio 2022 Debug X64 Version: NVIDIA-SMI 516.94 Driver Version: 516.94 CUDA Version: 11.7

In the sample memMapIPCDrv, seems like memory does not release to the OS (Both GPU memory and CPU memory) utile child process exit. Is this a bug? or I miss some cleanup?

PS.

• I change DATA_BUF_SIZE to 4G.
• I move the cuMemRelease in parent process ahead of waitProcess, and both child process and parent process pause just before call exit.
