[uClibc]Uses a bigger busybox more mem for (f.i.) ash?

I don't think this statement is true for non-MMU systems. The current uClinux
kernel (for ARM) loads the complete .text segment into memory. A subsequent call
to busybox loads the .text segement again. To my understanding there is
no sharing of code pages possible on non-MMU systems, since the code is relocated each time. In this case the actual size of the busybox .text segment (and .data, .bss as well) does
matter.
