/*
 *    This routine does a series of writes to an array.  This should cause
 *    the write buffer to be flushed.  At some point in time we may want to
 *    make this a system call, but the problem is that by the time you
 *    do the context switch and get to call the wbflush() kernel routine
 *    the write buffer will already be flushed (because of other writes).
