TypingsInstaller in 2.0.7 produces constant CPU load and high IO rate

[dbaeumer]

TypeScript Version: 2.0.7

Steps

• use a VS Code insider build from here: https://az764295.vo.msecnd.net/insider/ebd2a0126e37e45b33e868e11767e19888dd081b/VSCode-win32-1.8.0-insider.zip. This has TS 2.0.7
• clone vscode
• run scripts\npm.bat install (See here for the prerequisites https://github.com/Microsoft/vscode/wiki/How-to-Contribute#build-and-run-from-source)
• clear TS global typings cache
• open VS Code on the cloned vscode workspace
• open gulpfile.js

Observe: you see constant CPU load (2 - 4 %) and a high IO rate in the typings installer even after all typings have been installed successfully:

• close VSCode and reopen:
• you still have quite some CPU load on the typings installer and IO rate although it is less as when the typings installed actually installs types
