Emacs enters in a loop with emacsclient -t

Hi,

I'm running Emacs trunk r111924 on FreeBSD 9.1-RC3 (amd64). When I connect to
Emacs session using 'emacsclient -t', I noticed flicker in xterm. I truss-ed
Emacs process, and it seems like it's sending same stuff in a loop which seems
to be causing what I noticed:

The flicker stops, when I focus the X11 frame, and do some activity there, and
resumes when I focus back to xterm.

Following is configure options:

--localstatedir=/var --with-x-toolkit=gtk3 --with-xft --with-m17n-flt --with-libotf --with-imagemagick --with-gsettings --with-gconf --with-xim --with-sound --with-dbus --with-xml2 --with-gnutls --with-acl --x-libraries=/usr/local/lib --x-includes=/usr/local/include --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ --build=amd64-portbld-freebsd9.1 CFLAGS='-fstack-protector -g' CPPFLAGS='-I/usr/local/include' LDFLAGS=' -L/usr/local/lib -Wl,-rpath=/usr/local/lib'

I'm wondering if anyone else has noticed it, or know of a fix to the problem.

Thanks
