System.IO.Pipes.Tests.Perf_PipeTest hangs on Unix

[mellinoe]

This test seems to hang when run on Unix. There are a couple of threads waiting on PipeStream writes and socket loops. To repro, just run this test project:

Tools/msbuild.sh src/System.IO.Pipes/tests/Performance/System.IO.Pipes.Performance.Tests.csproj /t:rebuildandtest /p:outerloop=true

No tests are currently hanging.

It seems like this is because it is disabled in the base class.

    [AllowedOperatingSystems("Hangs on non-Windows, dotnet/corefx#18290", OS.Windows)]
    [BenchmarkCategory(Categories.Libraries)]
    public abstract class Perf_PipeTest : PipeTestBase

When I remove that test hangs on my Ubuntu 18.04. I will take a look.

Ugh. Thanks

It seems like it was dotnet/performance#56. I tried to move this to perf repo but I did not figure out how. Corefx/runtime tests do all pass so it seems like a problem with the perf test.

It seems like a test bug in perf repo. Closing since there is nothing left here.
I'll reopen dotnet/performance#56 and I'll submit fix there.
