Jail == place of execution? That's not the sort of ideological freight that I care to bring into my IDE. I'm sure you didn't mean it this way, but it comes off as gratuitously offensive.
I was really puzzled by this comment. At first I thought maybe you were joking, but you don't seem like you're messing around. In case you're really not aware, "jail" is long-standing terminology for a restricted environment. I'm not sure which is older, chroot or jail, but I think they both go back at least 15 years.
I am well aware of this, although I think it's a poor choice. But it's the juxtaposition wiht the word 'execute' that is problematic. If it was a secure place to 'run' unverified code I would not have an issue with it.
