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).
