Yes, and I tested (compile-time selected) with and without network coding, and
(at run-time) with and without fragmentation (as I also bumped into the MTU
calculation problem later fixed by the patch on this list) -- any 32MB RAM
devices reboots after roughly 30 minutes due to OOM without substantial traffic,
if there is traffic then apparently even faster...
