Cleanup hung Windows processes (#94357) Follow https://stackoverflow.com/questions/40585754/powershell-wont-terminate-hung-process to see if the hung python process can be killed completely ``` C:\Jenkins\Miniconda3\python.exe -bb test_ops.py -v --use-pytest -vv -rfEX -x --reruns=2 --shard-id=0 --num-shards=2 "-k=not linalg_cholesky" --import-slow-tests --import-disabled-tests ``` The command `Get-Process -Name $process -ErrorAction Stop | Stop-Process -Force` doesn't stop this process as expect ### Testing 1. Spinning up a local python process on Windows runner `C:\Jenkins\Miniconda3\python.exe debug.py` 2. See that the process is runnning ``` Get-WmiObject -Class Win32_Process -Filter "Name LIKE 'python%' AND CommandLine LIKE '%debug%'" __GENUS : 2 __CLASS : Win32_Process __SUPERCLASS : CIM_Process __DYNASTY : CIM_ManagedSystemElement __RELPATH : Win32_Process.Handle="8812" __PROPERTY_COUNT : 45 __DERIVATION : {CIM_Process, CIM_LogicalElement, CIM_ManagedSystemElement} __SERVER : EC2AMAZ-S19AQ2Q __NAMESPACE : root\cimv2 __PATH : \\EC2AMAZ-S19AQ2Q\root\cimv2:Win32_Process.Handle="8812" Caption : python.exe CommandLine : "C:\Jenkins\Miniconda3\python.exe" debug.py CreationClassName : Win32_Process CreationDate : 20230208002358.569943+000 CSCreationClassName : Win32_ComputerSystem CSName : EC2AMAZ-S19AQ2Q Description : python.exe ExecutablePath : C:\Jenkins\Miniconda3\python.exe ExecutionState : Handle : 8812 HandleCount : 82 InstallDate : KernelModeTime : 312500 MaximumWorkingSetSize : 1380 MinimumWorkingSetSize : 200 Name : python.exe OSCreationClassName : Win32_OperatingSystem OSName : Microsoft Windows Server 2019 Datacenter|C:\Windows|\Device\Harddisk0\Partition1 OtherOperationCount : 1135 OtherTransferCount : 150908 PageFaults : 2442 PageFileUsage : 5020 ParentProcessId : 5396 PeakPageFileUsage : 5120 PeakVirtualSize : 4368465920 PeakWorkingSetSize : 9424 Priority : 8 PrivatePageCount : 5140480 ProcessId : 8812 QuotaNonPagedPoolUsage : 8 QuotaPagedPoolUsage : 63 QuotaPeakNonPagedPoolUsage : 8 QuotaPeakPagedPoolUsage : 63 ReadOperationCount : 88 ReadTransferCount : 519894 SessionId : 0 Status : TerminationDate : ThreadCount : 1 UserModeTime : 156250 VirtualSize : 4362371072 WindowsVersion : 10.0.17763 WorkingSetSize : 9592832 WriteOperationCount : 0 WriteTransferCount : 0 PSComputerName : EC2AMAZ-S19AQ2Q ProcessName : python.exe Handles : 82 VM : 4362371072 WS : 9592832 Path : C:\Jenkins\Miniconda3\python.exe ``` 3.
