Oh, you mean "make bootstrap"?  The answer is (a) don't do it very
often (mostly use colocated branches, even for typos vs. feature
branches), (b) plan well enough that I start the "git clone x y; cd y;
make bootstrap; make check" process before starting something else
that takes 20 minutes or so, and (c) work on XEmacs, where 80% of the
Lisp is not in the main tree (most especially not calc or Gnus!) so a
bootstrap and test can be accomplished in less than 20 minutes even on
a 5-year-old iBook G4.

That's much better than it used to be, and as you say a non-issue.
