Actual behavior

I was run python command in VSCode Terminal, with matplotlib.pyplot to draw picture, but after a while, a lot of powershell.exe processes were created in Windows task manager, and resulting in insufficient memory. This problem was disappeared when disabled this extension.

No powershell.exe process resides in Windows task manager

Steps to reproduce:

run sometimes then see windows task manager.

@DonJayamanne Can you update the vscode-extension-telemetry version to 0.1.0 and give @Tovey a vsix to try out the fix?

We were able to track down the issue https://github.com/Microsoft/vscode/issues/60585 to 1.0.5 version of application insights used by vscode-extension-telemetry. The latest version of vscode-extension-telemetry uses the latest version of applicationinsights which has the fix.
