Regarding Python and bjam, is the idea that Python is
an optional component of bjam, or required?
Right now, I just use the "build.sh" script on Unix to build
bjam, and start using it right away.

popen() functionality would be very useful to have in
the core of bjam that is always there, regardless if
you compile it with Python or not. 

The main issue I see is that
popen() is not implemented as _popen() Windows:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt__popen.2c_._wpopen.asp

I don't know if there are any semantic differences between popen()
on Unix and _popen() on Windows.

Why was popen() never implemented in the core of Jam? 
While not the prettiest of things, it is useful to sometimes 
shell out and execute various commands during a build process.
