Using ParallelizableAttribute/DegreeOfParallelismAttribute causes tests to hang mid-run

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Include these attributes in AssemblyInfo.cs:
[assembly: MbUnit.Framework.DegreeOfParallelism(8)] //(This can be anything >1)
[assembly: MbUnit.Framework.Parallelizable(MbUnit.Framework.TestScope.All)]
2. Run test suite (we normally use Echo, but this also happens in Icarus) with 
tests (we have 145 tests in this assembly) 
3. After about 1/3 of the way in, the test harness appears to hang.  If we 
attach a debugger to it, the threads window shows threads are in our test code, 
but literally hung.  The test harness never completes running the tests no 
matter how long we've left it.  We have even given it the weekend to run, and 
no progress changes.

What is the expected output? What do you see instead?
The test harness to finish running the tests.

What version of the product are you using? On what operating system?
Version 3.2 build 517

Could this be related to issue 147?

Do your tests share any state? Could it be deadlock/livelock? Can you provide a 
sample that replicates this?
