I haven't heard such talk before. There was talk of making it impossible to
compile without cyclic gc, and-- indeed --that was done for 2.3.

We never build without WITH_PYMALLOC defined anymore, so under the "if it's
not tested, it's broken" theory, it's already broken <0.5 wink>. OTOH,
there are really only two substantive WITH_PYMALLOC #ifdefs in the codebase,
and one of them just surrounds the bulk of the code in obmalloc.c. So as
untested features go, I bet this one is less problematic than
WITHOUT_COMPLEX (which is tested in many more places!).
