Thanks for the input. I see your point but would argue (in the most
friendly way) that the case you point out would be extremely rare, while
the reverse case is very common.  Adding sleep to the rarer case makes more
sense to me.  Again, I propose an option to mk that, IMO, would have wide
value.

Yes, I realize I can change my version of mk.  In that case, I could do as
I please.  I was hoping to either learn from the experience (perhaps there
is a good reason to have mk make the same stuff repeatedly), or be able to
contribute.

Thanks.

Blake
