That is right. --with-max-ips determines the number of "interface:"
entries in the config ;)

I believe the value 32 is a safety measure. pselect is (still) used for
nsd inter process communications (over anonymous sockets). With a high
number of interfaces, the chance on higher numbered file descriptors
(numbers > FD_SETSIZE) becomes larger.

I'll review thoroughly the coming two weeks and return to you with a
