Thanks @davidbrochart, that works fine when timeout on kernel occurred.
As it is useful on timeout reply from kernel only (I think), shouldn't we rename the parameter to error_on_timeout instead of error_on_interrupt ?

[davidbrochart]

It is an execute_reply error that we want to generate when the kernel was interrupted (by us) after an execution timeout, so more precisely it should be error_on_interrupt_on_timeout, but that's a bit long 😄
I'm fine with error_on_timeout too.
