Description

After investigating a strange behavior on running karma with TeamCity on Windows, I noticed the following issue.

When running the following command in PowerShell:

karma start --single-run | Out-File C:\test.out

The writing function is non-blocking/asynchronous & the written/piped data can be buffered, which could lead to some test results being lost.

Karma needs to ensure that all buffers have been drained or that the writing functions have completed (if they are non-blocking) before exiting the process.
