Steps to reproduce

This was seen only on CI machines. Test failure in export test case that is doing dsc config export | dsc config set. On local VMs this does not repro.

Error: IO: Broken pipe (os error 32)
Error: [-] resource export tests.Configuration Export can be piped to configuration Set 5.09s (5.09s|3ms)

Expected behavior

`dsc config export | dsc config set` always runs fine.

Actual behavior

Error above.

A broken pipe probably means that upstream dsc config export didn't exit cleanly and broke the pipe. Maybe we need to add tracing to how dsc handles child processes that don't exit cleanly (such as if the process test process panic'd).
