http://code.google.com/p/chromium/wiki/LinuxZygote * Move Chrome specific bits out of base * Move away from the idea of reserved file descriptors (which don't really work with zygotes) * Load resources before forking renderers (means that we don't need communication between the zygote process and the renderers) * Make sure that gdb works against the browser again * Make sure that we have different ASLR between the renderers and the browser. http://codereview.chromium.org/119335 (This is a reland. First landed in r18109, reverted in r18112.) git-svn-id: svn://svn.chromium.org/chrome/trunk/src@18291 0039d316-1c4b-4281-b951-d872f2087c98
