Why not "git mount" indeed!

At work, I have 3 very active branches and a slow build system. Right now, when I switch to a new branch, I have to rebuild everything. Being able to "git mount" 3 snapshots in 3 directories with three different build outputs would make switching branches faster.

3 working trees would be even better. I've been wondering if I can make another working trees by creating a .git/ directory and symlinking to the .git/objects and ./git/refs of my current repository. (I could use the environment variables GIT_INDEX_FILE and GIT_WORKING_TREE, but that would require setting and resetting them. Or using a different shell.)

So a true "git mount" that allowed mounting editable branches would be very useful to me. (Although, if it wasn't for that crappy build system, I prefer a single working tree.)
