> I would doubt but there could be some source of problem in smp on the Win32 platform, since there was a SPINE implementation on an intelligent NIC with 2 embedded MIPS CPUs, perhaps this was just a driver RT but it was for real time and in such a case there should be no problem besides that of the scheduling policy, but thinking how about linking MS Win2k R is a kind of crazy not to believe there was some synchronization with CPU board threads and that component threading at some point I believe.
