[Boost-build] Ignoring -jN when linking executable targets?

Hi,

Does anyone know why bjam ignores the -jN option if the only targets  
to build are executables to link?  In this case you can see that  
there are 38 targets to build, all of them executables to link, and,  
you'll have to take my word on this, it serializes all the links even  
though I asked for a parallel (-j2) build.

-bash-3.00$ bjam --v2 -j2 --infinibanddir=/apps/x86_64/mpi/mvapich/ 
gcc-3.4.6/mvapich-0.9.8-ofed --builddir=/tmp/kbelco/nightly --g77dir=/ 
usr/bin/g77 --mkldir=/projects/global/x86_64/libraries/ 
l_mkl_p_8.0.1.006/lib/em64t --address-model=64 gcc-3.4.6 link=static

Has anyone seen this before or is this a known feature?

Thanks,
