BusyBox, uClinux, telnetd and shared memory

Hi,
I hope someone can help me with a quick question, or at least tell me
where to go to read more on the subject.
I'm pretty familiar with MMU Linux and have read a fair bit about how
uClinux differs. But I'm still not sure about the best approach regards
using daemons such as telnetd with BusyBox.
If I launch telnetd, I guess that BB does a vfork and then execs BB
again to run the telnetd applet. Will uClinux share the code pages
involved (which are loaded from a cramfs) or am I best minimising
memory usage by building a separate BB executable that contains only
the telnetd applet?
Ditto for the shell that telnetd will launch - build into a single copy
of BB or have a separate executable?
Thanks
Ian
