WSL 2.5+ slows dotnet when attaching debugger

### Windows Version

Microsoft Windows [Version 10.0.26100.3624]

### WSL Version

2.6.0.0

### Are you using WSL 1 or WSL 2?

- [x] WSL 2
- [ ] WSL 1

### Kernel Version

_No response_

### Distro Version

Ubuntu 24.04

### Other Software

dotnet 8
vscode (vsdbg)
netcoredbg

### Repro Steps

- Start WSL2
- Start a rather large dotnet8 application
- Attach a debugger, either vsdbg via VScode WSL or netcoredbg

### Expected Behavior

The application should run smoothly or just about the same as before the debugger was attached.

### Actual Behavior

The application is about 100x slower (literally) after the debugger is attached.

Start by reproducing the slowdown with the listed WSL 2, Ubuntu 24.04, .NET 8, VS Code vsdbg, and netcoredbg setup. Review the attached diagnostic logs and compare performance before and after debugger attachment; done means the application remains roughly as responsive after attaching either debugger.
