Impossible to use golangci-lint on vscode/go.12

Using the following settings on vscode

    "go.lintTool": "golangci-lint",
    "go.lintFlags": [
      "--config=${workspaceFolder}/.golangci.yml",
      "--fast",
    ],

Please include the following information:

1. Version of golangci-lint: golangci-lint --version (or git commit if you don't use binary distribution)

I can't even get the version

 golangci-lint --version
Error: unknown flag: --version
Usage:
  golangci-lint [flags]
  golangci-lint [command]

Available Commands:
  config      Config
  help        Help
  linters     List current linters configuration
  run         Run this tool in cloud on every github pull request in https://golangci.com for free (public repos)

Flags:
      --color string              Use color when printing; can be 'always', 'auto', or 'never' (default "auto")
  -j, --concurrency int           Concurrency (default NumCPU) (default 4)
      --cpu-profile-path string   Path to CPU profile output file
  -h, --help                      help for golangci-lint
      --mem-profile-path string   Path to memory profile output file
  -v, --verbose                   verbose output

Use "golangci-lint [command] --help" for more information about a command.

It's basically now impossible to use vscode with golangci-lint because just after starting to type everything gets super slow and I can see on my activity monitor 5 different processes for golangci-lint each one with 1GB ram usage.

Hi, thank you for reporting!

1. In the newest version (no release, only in master) only one golangci-Lunt can be run at one moment
2. We have dramatically reduced memory usage in the v1.20.0
