[BUG] the output of the publish and postpublished are mixed up

[pygy]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

The upload bar of the publish script keeps being updated while the postpublish scripts are running, resulting in garbled output:

Here's a sample starting with four lines of adequate output then the rest where the progress bar is mixed with the postpublish output:

npm notice total files:   19

Expected Behavior

postpublish should start when publish is done.

Steps To Reproduce

Create a package with a postinstall script that prints to stdout, run npm publish.
