I would be genuinely interested to know about another project which is
geared up to be resilient against kernel hangs so that we can borrow
some ideas on how to reliably detect kernel soft lockups or syscall
hangs. As far as I know, even mature projects like Apache have not
bothered fixing such hangs (or even detecting this kind of underlying
OS flaw).
