Ok. First, I observe the same behaviour with bjam -n.
It uses 230 MB for header-scannning, I think and then starts using up
memory while putting out 20x "patience".

I've done a quick check with M5 and it works fine. It needs 228 MB for
the first step (header-scannnig) and then about 260-280 MB.
The interesting thing is that M5 reports

bjam Version 2
...patience...
4x patience
...patience...
...found 25611 targets...
...updating 1 target...

and M6 (current CVS) reports:
bjam Version 2
...patience...
22 x patience
...patience...
...found 39385 targets...
...updating 1 target...

So, M6 even somehow "finds" more targets then M5. Any Ideas ?

Yours, Jürgen
