Actually
there's one exception: running under SunOS 4. That was ages
ago of course. It did SMP, but only one CPU can be in the kernel at
once (one big lock!) so system calls were a big bottleneck.
Was SunOS 4 SMP? I thought that was the whole point of Solbourne making
OS/MP, because SunOS *wasn't*.
