It's never been a problem, and aside from these few straggler threads, everybody has effectively been there already for years, so if it were a problem someone would've complained by now.
Also; like said before, the admin had better configure.
Also also, RR-SMP is actually broken (and nobody has cared enough to bother fixing it).
