There are two problems:
1 pipelining
2 physical pin level

Adding nops solves 1 and might solve 2, depending on the external load
and the number of nops. Or put it in a more harsh way: assing nops is
*not* a solution. Just use a shadow register, that solves both problems.
BTW the Jal IO routines use a shadow register, invisible to the casual
user. One more argument for using a HLL...
