Lots of similar issues to this. All seem to have a common symptom: "Text file busy"

https://runfo.azurewebsites.net/search/tests/?bq=definition%3Aruntime++started%3A%7E3&tq=message%3A%22Text+file+busy%22

I believe this is Unix's version of "file in use" for the executable you're trying to launch. From what I read, this should only happen when a write handle is open on the executable. This could be a product bug like someone forgot to Dispose a handle. The tests are seeing it because they are writing the exe in proc then running it immediately afterwards. We should examine the bundler codepath to make sure it disposes all files.

Edit: product code seems to protect against this:

runtime/src/installer/managed/Microsoft.NET.HostModel/Bundle/Bundler.cs

Line 223 in 0403018

using (BinaryWriter writer = new BinaryWriter(File.OpenWrite(bundlePath)))

Perhaps these tests are running concurrently with the same path?

[agocke]

Yeah this is interesting, we should investigate.
