can't you simply ask some juniper employee? anyway - from where did you 
got that info about network stack being rewritten?

once again - first ask WHAT EXACTLY FreeBSD is doing in their router?

a) just preparing tables for router chips? - then FreeBSD's network stack 
is OK
b) actually performing part of routing activity cooperating with ASIC's?
if so - rewriting/modifying network stack was needed for sure.
