BreadBoard
I'm starting a revision of the system. I'm putting shared libraries in. My original root module was all static, but I'm trialling it with shared libs, and the space saving appears to be quite substantial. I'm keeping various critical binaries static, almost everything is dynamic. I'm also writing a script for the build process. I should probably be doing it in make, but I'm doing it in perl for the moment, because I need it quickly. =)
Squid
I'm starting to bolt Jonathan Lemon's kqueue into Squid as a replacement for select/poll. I'm also thinking about having a bash at bolting rproxy into Squid as well, but we'll have to see about that. =)
