Follow-up Comment #1, bug #3031 (project lwip):
This one would be of great interest for me, as I think embedded systems
running for a long time should not have a heap if memory is allocated ADN
deallocated often with different sizes. (And our devices have to run a looong
time, ~30 years is our goal)
Implementing fully pooled pbufs would be one step into that direction.
BUT: I think this would only make sense if mem_malloc() could be eliminated
for the rest of the core code. Since this is mainly dhcp and snmp, I hope
introducing new memp pools for those would be enough.
This could also solve the issue where no pbufs were free to acknowledge tcp
segments (which again would free some tcp enqueued pbufs). This was an error
report somewhere, though I don't remeber it.
I'm not planning to take on this right now, just wanted to know your
opinions.
