If you rebuild Privoxy from git it will use poll() instead of select()
so the FD_SETSIZE limitation isn't relevant for recent Linux systems
anymore.

If you want to stick to Privoxy 3.0.26 you can use a FreeBSD-based
system instead. Other systems that don't use the GNU libc may work
as well but I haven't tested them.
