Assuming mutual exclusion primitives (on the hardware) work OK, you can do that by careful design I guess. > Because if you can prove it, go > ahead for Nobel prize), but it's for sure not very common (= almost > nobody use that) code path, so I would say probably no (that's why > corosync 2.x doesn't have threads at all). You are not going into details with the design (my question), but I guess if you allocate some memory under mutual exclusion from a shared pool, and each thread only works on that allocated memory, there should not be any race condition. So whats' the use of a threads parameter if corosync does not use threads???
