OnReceive Question

I have the following piece of code:

// this called when some data comes in
public void OnReceive( IAsyncResult ar )
{
// receive data
string message = ...;

// continue to listen
BeginReceive( ... );

// process string based on some condition
if ( condition )
{
ComplicatedProcessor( message );
}
else
{
QuickProcessor( message );
}
}

my question is: If the code ends up calling ComplicatedProcessor, and
before ComplicatedProcessor returns, there's an incoming message, will
OnReceive be able to be called again?.. meaning while the 1st
OnReceive's still running, can a 2nd one start?
From my experiment, the answer is no. Everyone know how can I get

OnReceive runs on a threadpool thread, so when a message arrives before the
ComplicatedProcessor method returns another thread will be pulled from the
pool to run OnReceive.
What makes you think the answer is no.

Let another thread handle the processing?

Why? Each OnReceive runs on a Threadpool thread, there is no need to spawn
yet another one.
