Interrupt shouldn't kill Juliaif nothing is running

[sglyon]

Right now if you do cmd+j cmd+i when julia is inactive, it will kill the active julia process. I believe this should be as simple as catching InterruptException() instead of doing whatever is printed here (nice that we can copy console output to show you this now :) ):

fatal: error thrown and no exception handler available.

At the moment the issue is that the InterruptException() bypasses the Juno worker tasks completely, which are stalled waiting for data from the socket. I'll think about it some more, there may be some way of injecting an interrupt-handling task or something.

Have you tried making interrupting julia a no-op when no user side code is running? Not sure if this would be a robust solution, though, but probably better than the current behaviour anyways...

[MikeInnes]

Yeah, just disabling it depending on the working status seems like a reasonable bandaid.

[MikeInnes]

Just pushed a patch for this. It actually seems to be reasonably robust, but let me know if it causes any issues.

Seems to be working for me, thanks!
