Description
Issue Description
Issue Type: Performance Issue
When using powershell (64 or 32) for around 5-10 minutes, running run code snip or debug will result in cpu spikes on powershell, and will hang in the integrated console for multiple minutes, even on a command that runs near real time.

Research direction
Start by reproducing the slowdown in the PowerShell integrated console after 5–10 minutes with the reported VS Code, extension, Windows, and PowerShell versions. Review the attached or emailed logs and compare run-code and debugging behavior; done means the CPU spike and multi-minute hang are no longer reproducible.
