Well, it's been...5 yrs since I filed that PR.

In that time, my brain has been scooped out and
replaced with that of a Java guy, so...I'm not
compiling NetBSD kernels any longer, my test
gear is all decommissioned, and I no longer
work on *BSD kernels for either a living or
a playing.

Sorry, but I can't help very much here, except
to agree with the obvious: a parallel make running
on a union'ed /usr/src would pile up a bunch
of concurrent accesses to the same dir structure,
so it seems that if PR 32535 is fixed, then this
one would be, too.
