Please update and rebuild Boost.Jam. Then, put the following in your Jamroot:

        import modules ;
        modules.poke : PARALLELISM : 4 ;

and it should have the same effect as -j4 on command line. Presently, the PARALLELISM
variable overrides -j option. Soonish, I'll make it so:

- you can create file project-config.jam, containing:

        option jobs : 4 ;

and have 4 jobs by default

- you can use --jobs=10 on command like, overriding project-config.jam

Let me know if the Boost.Jam change works for you, and if the future directions
seems right,
