The ehttpd code was sent by Wei (first email). Here it is again (attached).

You also need his patched version of the VM. More precisely, the "bind_port_to_scheduler" 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
make clean
CFLAGS="-DERTS_POLLSET_PER_SCHEDULER -g -O3 -fomit-frame-pointer" ./configure --prefix=/SOMEWHERE/usr
make && make install

Then:
export PATH=/SOMEWHERE/usr/bin:$PATH

Regards,
Zabrane
