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!
