/****** posbb_tests.c/Test_CopyMem ******************************************
*
*   NAME
*     Test_CopyMem -- Tests speed of memcpy()
*
*   SYNOPSIS
*     time = Test_CopyMem( void )
*
*     int Test_CopyMem( void );
*
*   FUNCTION
*     Does 100,000 CopyMem() of a 1024 bytes memory block and returns the
*     time it has spent.
*
*   RESULT
*     time - number of seconds it took to do all memory copies.
*            TRUE if something went wrong (usually lack of memory).
*
*   EXAMPLE
*     Examine posbb.c/Perform_Tests().
