If I understand you correctly, these are great news. So, using M6 and bjam as 
of 2003-07-09, you had lots of memory eaten. Version from 2003-07-10 works 
ok. On "2003-07-09 09:49" Moscow time I've comitted fix for a serious bug, 
and this can account for the difference. The bug was logical, but it would 
not surprise me if it caused increased memory consumption.

It at all possible, can you try build the CVS HEAD state of jam and see if it 
works OK?

I'd really wish that Boost.Build was hosted in Subversion repository. Instead 
of those dates and timezones, we'd have a single revision number to talk 
about.
