What versions & operating system are you using?

No response
Describe the Bug
If you have multiple files, n, modified at the same time, then the build will start n times at the same time. This should probably either not start if a build is in progress and/or wait a fraction of a second before starting and ensure it only kicks off once even if it saw multiple files change.
Please provide any relevant error logs
