Comment (by Tino):

 Additionally, parallel builds can only be hardcoded to a specific number.
 AFAIK bjam can not use a make jobserver in the case that boost is only one
 part of the whole build process.

 I have a build system that builds several software packages for several
 architectures in one run. I can specify make -j<number> and the make
 jobserver will use the specified number of jobs.

 Except for Boost. I have to hardcode a fixed job number for the boost
 build (like bjam -j4), that leads to either unused CPU cores, or a lot of
 overhead, depending on the number of target architectures that are built
 and the number of CPU cores usable.
