a lot of (mostly empty) /tmp/go-build* folders

[OneOfOne]

Dup of #2173 and #2403.

/tmp/go-build762230263/b294:

/tmp/go-build762230263/b299:

The majority of those folders are empty, however one of them have 2 empty sub folders.

Latest stable vscode-go extension as of posting this.

My guess is the extension (or gopls) kills the go build before it finishes cleaning up.

Yes, according to the recent #gopls slack conversation, this is related to golang/go#21135. @stamblerre can you transfer this bug to upstream?

[stamblerre]

Opened golang/go#37368.

[stamblerre]

Closing in favor of that issue.
