[flakey test] The I/O operation has been aborted because of either a thread exit or an application request.

Spotted an odd one on CI

System.IO.IOException: Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request..
 ---> System.Net.Sockets.SocketException (995): The I/O operation has been aborted because of either a thread exit or an application request.

Seems to be related to:

dotnet/runtime#26629

RavenDB seemed to have similar issues and found it was related to Process inheriting handles. We have a similar situation where Elastic.Managed.Ephemeral boots Elasticsearch as child process.

We'll need to look adding this option to https://github.com/nullean/proc
