Is It Possible To Create Thread && Start From CLR Stored Proc

My simple CLR Stored procedure is as below:

[Microsoft.SqlServer.Server.SqlProcedure]
public static int MyParallelStoredProc(string name1, string name2)
{
Thread t = null;
Worker wth = null;
int parallel = 2;
Object[] obj = new object [parallel];
SqlPipe p;
p = SqlContext.Pipe;

for (int i = 0; i < parallel; i++)
{
if (i == 0)
wth = new Worker(name1);
else
wth = new Worker(name2);
t = new Thread(new System.Threading.ThreadStart(wth.WorkerProc));
t.Name = "Thread -" + i.ToString() + ":";
t.Start();
p.Send(t.Name + ":Started");
obj[ i] = t;
}
for (int i = 0; i < parallel; i++)
{
t = (System.Threading.Thread)obj[ i];
t.Join();
p.Send(t.Name + ":Finished");
}
return 0;
}

The worker class implementing Thread Proc:

public class Worker
{
private string Name;

public Worker(string name)
{
SqlPipe p;
p = SqlContext.Pipe;
Name = name;
p.Send("In Constructor:" + Name);
}

public void WorkerProc()
{
SqlPipe p;
p = SqlContext.Pipe;
for (int i = 0; i < 10; i++)
p.Send(i.ToString()+":"+Name);
}
}


The assembly is registered with UNSAFE permission set.

CREATE ASSEMBLY
ThreadTest
FROM
'C:\ThreadTestinDebugThreadTest.dll'
WITH
permission_set = unsafe;
GO

CREATE PROC ParallelStoredProc
@Name1 NVARCHAR(1024),
@Name2 NVARCHAR(1024)
AS
EXTERNAL NAME ThreadTest.[MyTest.ThreadTest].MyParallelStoredProc


When I invoke the the stored procedure from T-SQL script as below,

EXEC ParallelStoredProc @Name1, @Name2

the thread class constructor gets called; but the 'WorkerProc' does not execute ?



Whether an UNSAFE assembly is allowed to spawn threads

inside SQL Server ?
