UMA refcounting is gone as of r296243, so this bug no longer exists. In
particular, it's now possible to guard mbuf clusters with memguard.

.Sh BUGS
It is not possible to guard allocations that really expect themselves to be
allocated from
.Xr uma 9 ,
utilizing additional interfaces apart from
.Fn uma_zalloc
and
.Fn uma_free ,
for example
.Fn uma_find_refcnt .
For the moment of writing only
.Xr mbuf 9
cluster zones belong to that kind of allocations.
Attempt to guard them would lead to kernel panic.
