Describe the bug

I have some problems with "interrupt" or "shutdown" kernel reply.

• 1 launch python3 kernel
• 2 run while True code
• 3 click menu "Runtime--Kill" or "Runtime--Interrupt"
• 4 debug on chrome dev tools
• 5 timeout occur.

Another problem is: the interrupt action cannot run python del function. Just like python repl mode, user send "ctrl+c" keyboard action.

• OS: Windows 10 x64
• Version 0.28.0

I found the root caurse. When "while True" code running, kernel can't reply new "execute_request".
