I'm sure we are, this is just hard to check, because we don't have
list with allocated 'cred' structures.

But try to do your test without a jail and track 2nd column in:

	# sysctl kern.malloc | grep cred

Number of objects grows when I'm killing daemon while connection
exists. I'm wondering if this cannot be used to some DoS attack.
