It depends on how much you need to pull in. Thanks to Xcode and Safari
which eat up all my RAM on a 8GB maxed out system, I personally have
little to spare. For small BSD tools with no dependencies on things
like Cocoa, I expect it to be small.
I recently tried a 32-bit Quicklook plugin. Using it causes a separate
daemon process called QuickLook_legacy or something to launch. Were
talking small amounts of memory fortunately, but this is another
example of the kinds of side-effects.

I think I saw somebody callout a fairly popular text editor recently.
One other consideration though is 32-bit (i386) only bugs. I suspect
Apple is not testing i386 much any more and I have been hit by several
annoying i386 only bugs. I had one or two annoying, but non-critical
ones related to CAOpenGLLayer/OpenGL/video card drivers and fullscreen
transitions in 10.7. In 10.8 I just hit one in 10.8 with the network
reachability APIs where nothing returned the correct results. I had
already been working on a fork for my codebase that moved to 64-bit
for awhile now, so this issue was the final straw that broke the
camels back and we scheduled an emergency/earlier-than-planned merge
to get this into our mainline branch instead of continuing on with the
buggy 32-bit side of things.
