NNTP TLS and COMPRESS support and cgit spawning from
the WWW interface were implemented last year.
Given the lack of syscall number stability guarantee on the
OpenBSD and FreeBSD, I don't think supporting a pure-Perl kevent
is feasible. Inline::C may still be an option since IO::KQueue
is abandoned, though, as it is for some Linux-only syscalls and
maybe some POSIX ones not covered by POSIX.pm.
