/* In order for the DH/DSA timing tests (which use cryptlib-internal
   mechanisms) to work, it's necessary to add the following lines of code to
   the start of cryptDeviceQueryCapability() in cryptapi.c, before any other
   code:

	if( cryptAlgo == 1000 )
		return( krnlSendMessage( device, IMESSAGE_SETATTRIBUTE_S,
								 cryptQueryInfo, CRYPT_IATTRIBUTE_KEY_SPKI ) );
	if( cryptAlgo == 1001 )
		return( krnlSendMessage( device, IMESSAGE_CTX_ENCRYPT,
								 cryptQueryInfo, sizeof( KEYAGREE_PARAMS ) ) );
	if( cryptAlgo == 1002 )
		return( krnlSendMessage( device, IMESSAGE_CTX_DECRYPT,
								 cryptQueryInfo, sizeof( KEYAGREE_PARAMS ) ) );
	if( cryptAlgo == 1003 )
		return( krnlSendMessage( device, IMESSAGE_CTX_SIGN,
								 cryptQueryInfo, sizeof( DLP_PARAMS ) ) );
	if( cryptAlgo == 1004 )
		return( krnlSendMessage( device, IMESSAGE_CTX_SIGCHECK,
								 cryptQueryInfo, sizeof( DLP_PARAMS ) ) );

   This is because the DH/DSA tests are handled by passing magic values into
   the function (which is very rarely used normally).  Remember to remove
   the magic-values check code after use!

   Under Unix, the test code can be built with:

	cc -c -D__UNIX__ testtime.c
	cc -o testtime -lpthread -lresolv testtime.o -L. -lcl

/* Print timing info.  This gets a bit hairy because we're actually counting

	1. Take the fastest time, which will be the time least affected by

	2. Apply standard statistical techniques to weed out anomalies.  Since

	   more rigorous approach is to discards results more than n standard

	   context switch of 20K ticks can throw out results from an execution 
	   time of only 50 ticks.  In any case (modulo context switches) the
