As I expected, the tag limit has 0 subscribers, likely because it does not make a lot of sense... it is too general. Can we just ban it.
What? The tag is perfectly cromulent. A limit is traditional unix terminology for imposing that a program uses a maximum amount of a certain resource (memory, CPU time, open files, etc.), as in the Csh
limit command, the Bourne shell
ulimit command, the
setrlimit system call.
That the tag has no subscriber is irrelevant. This is not a subject in which there is much focused expertise — you don't see many people who are an expert in limits, like there are OpenBSD experts and Gnome experts and so on — so it is natural that the tag has no subscriber. However, the tag has an unambiguous meaning and is useful in searches. There's absolutely no reason to ban that tag.
