Can Mozilla Thunderbird show sent replies in threaded view?

I would like for Thunderbird to show replies to threaded messages in with the received messages. Is this possible, even with an extension? The desired behavior would be something like how Zimbra's threaded email view works.

When you start multiple threads on a multi core processor, are they guaranteed to be processed by different cores?

I have a Pentium core i5 processor, which has 4 cores. If I do this in a C# console program var t1 = new Thread(Thread1); var t2 = new Thread(Thread2); t1.Start(); t2.Start(); are t1 and t2 threads guaranteed to run on separate cores?

What is a user thread and a kernel thread?

I know what a thread is, and I know how they work, but I'm quite confused as to what a user thread and a kernel thread are in terms of what they are allowed to do. Can you please clarify what a user thread can do and what a kernel thread can do?

Does the Windows scheduler allocate equal length quanta to threads?

Is the time slice (quantum) that the Windows Kernel Dispatcher allocates to threads the same length for every thread, or does it base the size of quantum on the priority of the thread like Linux does?
