With -CURRENT up to 2006-02-12 06:57:41 UTC (last commit by scottl)
I still can see some calcru messages:

calcru: runtime went backwards from 3508844 usec to 3508842 usec for pid 28 (pagezero)

There are no repeated messages about madplay, as it was before. CPU is 
overloaded in this test (usually each madplay process uses about 12% on my 
system, and in this test each process has only about 7% of CPU to run. In 
normal conditions only one or two are running, other are in 'pcmwr' state 
(according to top), in overloaded system all madplay processes are 
'running'.
