On Windows, howl tests may take a very long time #42

Tests will run very slowly, with a complete run taking 40 minutes in one instance and (consistent) apparently "hanging" Appears related to output redirection (same was observed on macOS, Linux before I turned off output redirection).

Same result with howl test . and dotnet test. Tests that do not invoke dotnet are probably not affected. Not observed in CI, perhaps a side effect of calling tests via gitbash?

Practical solutions here:

Add a flag to disable output redirection (will stifle dotnet output when running howl test . but not dotnet test)
Fix output redirection, if that is the root of the issue, and can be done.
Isolate related tests
