 *  class CDevCertKeyCreator

 *

 * Server side

 * Class to make key creation "asynchronous" by spinning off a thread

 * to make the synchronous call to the appropriate key creation function

 * The thread entry point is a static member of this class, which holds the 

 * thread and thread parameter data too.  When the key has been created, the

 * thread terminates using Rendezvous to notify the main thread.  The created key

 * is returned through the CAsymmetricCipher member of CKeyCreatorData
