Wheee! I jumped on the bandwagon and see very nice speedups:

Old bjam (r58428)
-----------------
OS        Kernel  User   Total  Cycles
Windows   36.1    50.6   86.7   229,623,936,632
Linux     0.7     25.9   26.9

New bjam (r75722)
-----------------
OS        Kernel  User   Total  Cycles
Windows   8.5     16.5   25.1   63,352,251,536
Linux     0.8      7.8   11.6

Times in seconds. Total is wall time on Linux, kernel+user on Windows (read from Process Explorer's 
Performance tab).

Thanks!
