Title: re-enter kernel.eventloop after catching SIGINT

As requested by @fperez

This protects the kernel from exiting due to bugs failing to catch SIGINT properly in the eventloop integration
functions, as described in #1228. It does not fix those bugs, only reduces the severity of their consequences.
