Prototype implementation of zygotes.
Limitations that need addressing still:
- Doesn't forcibly terminate children that should have exited but haven't
Enable with env var ENABLE_ZYGOTE_MANAGER=1.

start the browser, then make chrome and all .pak files unreadable; or alternately, start an installed browser, and uninstall the browser while it's running. Then create a new tab and browse to two new sites.
Here's an example script to hide and unhide the .pak files (note: do not move the directory they're in, that doesn't work):
#!/bin/sh
chmod_all() {
chmod $1 sconsbuild/Debug/chrome
for path in . locales obj/chrome/app/intermediate/repack obj/global_intermediate/* themes
do
chmod $1 sconsbuild/Debug/$path/*.pak
done
}
case $1 in
hide) chmod_all 000 ;;
show) chmod_all 755 ;;
