Follow-up Comment #4, bug #28775 (project lwip):

Maybe it's a bit late, but I'm not in favor of using SYS_LIGHTWEIGHT_PROT for
the socket array.
It's generally implemented by masking interrupts, and it's not good in my
case (for the same reasons as Frederic Bernon IIRC), so I'd rather stick to
semaphore or mutex.
We should let the choice to the user with an option, like
LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT.
