Arf ! while the test seems to run perfectly on mono processor SPARC
under linux, the test on my SS20 DualROSS 200 Mhz is a disaster :)
PB with linux SMP on sparc 32 ?

Machine: sparc. Sysname: Linux. Release: 2.2.24-rc3. Nodename:
fuckinlou.
Number of CPUs supported by system is unknown. Number of CPUs online is
2.

MHz.

this.)

Hope this help :)
