Yes, please find the gzipp'ed file attached.
I've not run the whole build, but maybe 80%. I commented out some 
small projects while playing around.
But I think this is still big enough ;-)

It looks _very_ fast. It's impressive: I'm seeing a speed improment of 
an order of magnitude. The response time for all libs is
just about 2 minutes.

Great Work, Volodya !

One glitch: I'm specifying an external lib with

lib LIBX : : <name>LIBX <search>/usr/local/LIBX/lib/linux-g++ ;

in toplevel-Jamfile, but bjam does not add a -L path option to the 
linker, but only -lLIBX. So linking fails for me at the moment.

Yours, Jürgen
