Comment (by Hello71):

 I think protocol_list_supports_protocol fixed by rust protover. I think
 dgoulet is working on outbuf_table_add. I looked at cell handling but I
 think a lot of that work overlaps with
 https://lists.torproject.org/pipermail/tor-dev/2017-October/012536.html.

 excessive malloc/free could also be mitigated by switching to jemalloc on
 Linux #20424-ish
