[Dovecot] bug in 1.0RC2? (i guess this is kqueue problem)

fbsd6.1, dovecot using TLS.
--with-ioloop=kqueue solved the problem.

dovecot --build-options
Build options: ioloop=kqueue notify=kqueue openssl
SQL drivers:
Passdb: checkpassword pam passwd passwd-file
Userdb: checkpassword passwd prefetch passwd-file static

I noticed in rc1, the default for --with-ioloop is kqueue but in rc2, it
changed to poll.
