As you've correctly identified, a lot of the current code assumes that the number of online CPUs is static. I don't think anyone is working on fixing this at the moment, but I'd be happy to merge patches that rectify this assumption if they are not too intrusive.</div><div><br></div><div>Thanks,</div><div>Björn</div><div><br></div><div>PS: In the future, please subscribe to the list before posting; due to spam issues, I need to manually process each post by a non-member.
