can't compile the VM wihth your new patch:

git clone git://github.com/weicao/otp.git
cd otp
git fetch git://github.com/weicao/otp.git bind_port_to_scheduler
./otp_build autoconf
CFLAGS="-DERTS_POLLSET_PER_SCHEDULER -g -O3 -fomit-frame-pointer" ./configure --prefix=/SOMEWHERE/usr
make && make install
make clean (WITH OR WITHOUT make clean, it doesn't compile)
make
[...]
