Don't disable GC during init
Don't disable GC during init

I just got hit by another unintended side effect of disabling GC,
which is that init gets super slow when you're installing lots of
packages. Disabling GC doesn't seem to actually speed up init all that
much, and can cause a lot of trouble, so let's not do it.
