Architecture: x86_64
Machine: amd64
>Description:
Since updating to a NetBSD 7.99.4/amd64, my pbulk on tmpfs has much
lower success rate. Quite a few packages fail due to

Can't opendir(./Source/WebCore/loader/soup): Permission denied

or directly make(1) reporting permission denied for '.'.

The kernel before that was Jan 9 (also 7.99.4), I don't remember that happening that
often, but I'm quite sure it didn't happen with my 7.99.3 from Dec 22.

I had seen similar problems in the past, but with lower frequency,
and not at all for a number of months now.
 
>How-To-Repeat:
Do a pbulk on tmpfs.
>Fix:
Please!
