No I have not gotten to 4.2.1 yet.
I have experimented using j values ranging from 16 to 64. The majority of the
testing is with -Otarget. But I have tried all of them.

Assuming you determine the behavior exists even in version 4.2.1, please
provide more details. What level of -j are you using? Which sync mode are you
using? Do you get the same behavior even with lower levels of -j, if yours is
very large?
