I think this IS a problem. We need a per-process mask. to block signals that no thread is interested in. Since M:N threads do not have a kernel thread for each userland thread, there is nowhere to store this info any more. I'd be happy to have it be a per-ksegrp mask actually.. (to help deliver the signal to the right group to lower the interaction between UTS's in different groups.)
