 *
 *  XXX This isn't great since addresses are not uniformly distributed.
 *
 * PARAMETERS:
 *  "object"
 *      Address of Object to compute hashcode for. Must be non-NULL.
 *  "pValue"
 *      Address where PKIX_UInt32 will be stored. Must be non-NULL.
 *  "plContext"
 *      Platform-specific context pointer.
 * THREAD SAFETY:
 *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
 * RETURNS:
 *  Returns NULL if the function succeeds.
 *  Returns a Fatal Error if the function fails in an unrecoverable way.
