Google Chrome - Extensions run in separate processes too

At some level I knew that extensions for Google Chrome ran in separate processes too, but I never really gave it a lot of thought till I was in process explorer today and saw a bunch of chrome.exe processes taking up memory, a little more investigation showed that it was all the extensions that I was using that were causing the multiple processes running even for one open tab. I am going to cull the extensions today to the bare minimum because Chrome is running for me almost 100% of the time and I cannot have nice-to-have extensions taking up the memory.
