IMO, it would be a very bad mantra for a Lisp package operating on
this low level to disable GC, because that could cause the user's
system to run out of memory, and Emacs be killed by the likes of OOM
killer agents.  Disabling GC is barely a good idea on the
user-customization level, certainly not in packages such as undo-tree.
