A bootstrap takes more than half an hour on my machines.  Having touched
one C header file means that rebuilding takes almost 10 minutes here.
Calling that "annoying" would be an understatement.  Having multiple
clones is an essential prerequsite here.

This is my workflow as well.  Which doesn't exclude that git's branching
concept might be useful even here.  Sometimes, at least.

Among others, the switch to MSYS has made building on Windows slow down
by a factor of two here (at least that's the impression I get).  And I
never gave bisecting a thought on my machine even before that change.
In addition, recent changes to C mode has made editing C files slower by
a factor of two here.  So I'm hardly going to tolerate further slowdowns
caused by switching branches.

Mine might be an exotic case and the only useful recommendation for me
is probably to get myself a new machine.  Nevertheless I doubt that all
Emacs users have suitable hardware that makes switching between master
and Emacs-24 a feasible operation in one and the same clone.
