There should be also problem with floating point implementation on
client and server side. For example if somebody use floating point
optimalization (-fast switch in Sun Studio) for server compilation and
client will be connected from another machine with standard floating
point behavior. Result could be wrong.

Some multi core/thread CPUs has only one FPU (e.g. Niagara).
