[plt-scheme] 3m defaults to --enable-account

Hi.
I was wondering, in the midst of this debate -- is it harder to use 3m
when embedding C extensions in mzscheme? The nice thing about the
conservative collector, as far as I understand, is that you can pass
around collectible and noncollectable pointers pretty freely, i.e. have
a collectible pointer pointing to a noncollectable pointer.
