Comment:

 These interrupt handlers have been rather flaky but the code hasn't
 changed the 8 years since they were written I think. The runtime will
 immediately kill the process if it receives two ctrl+c after each other. I
 suspect that something with threading is messing up again and handling the
 same event twice.

 But will need to investigate to be sure, but seems related to #3081
