Follow-up Comment #12, bug #52763 (project lwip):

> Up to now, worst case calculation was deliberately used in lwIP to prevent
"random" allocation failures when the heap gets empty. 

Yes, I see that resource management strategy dominating lwip. On a limited
device such guarantees can not be met, however with some resource management
it might still be reliable enough for the job.

> LwIP does not use the C heap!

Sounds like a barrier to attempts to manage the memory resource and with that
barrier there seems no point in pursuing the mdns changes.

> And regarding the separatoin of big changes into small commits: I also think
it's important to have one issue solved per commit. That doesn't mean commits
have to be small, but mixing things in one commit makes it really difficult to
see what has change why when you look at it ten years later...

There is nothing constructive I can add, small commits are good, but I just
don't have the resources.
