Bug ID: 42542
           Summary: winetricks dotnet46 hangs frequently (mscorsvw.exe)
           Product: Wine
           Version: 2.2
          Hardware: x86
                OS: Linux
            Status: NEW
          Keywords: download, Installer
          Severity: major
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
        Depends on: 42470
      Distribution: Gentoo

This is related to bug 42470. There seem to be two separate issues
A) frequent critical section timeouts, native msvcrt seems to help here (and
potentially Dmitry's patch from bug 42470, but B) makes that hard to verify)
B) this issue. mscorsvw.exe from dotnet20/dotnet40 frequently hang:

This was in a loop running winetricks-test dotnet 100 times. This particular
run failed on try 11. It's been hung for at least 7.5 hours:
Sun Feb 26 12:35:33 CST 2017

These two issues are making it difficult to run winetricks-test (and I suspect
are the source of a lot of recently filed winetricks bugs regarding dotnet.

I'm not sure what logs would be useful here, but I'm happy to get whatever
would be useful.
