Need some understanding on expiry thread

[Guillaume Quintard]

Hi,

There are people better suited to answer this, but hopefully, they'll yell
if I'm saying anything stupid.

After a cursory glance at the code, I'd say that objcores can be expired
either from the inbox or from the binheap and that if you find a "posted"
oc on the binheap, it's the inbox turf, so we null the oc to not handle it
in the rest of the function.
