It mighe be OOM, for every packet we mmap 10MiB chunk of memory.
Which is *not* unmaped in emem_free_all() nor ep_free_pool().
(AFAIR for performance reasons)
Generally it'd be best to save somewhere mem->free_list before
1333 g_free(mem);
If it's hard to do than emem_destroy_chunk() is your friend.
[PS: I haven't test it yet, but looking at diff it makes sense,
if not please move on ;)]
Cheers,
Kuba.
