Can’t stop WEBrick 1.3.1 with ctrl-c on Ubuntu 11.04

I’d rather comment than add an answer for this, but not enough rep.

I have the same issue and found that resuming (with fg) after typing ctrl–c then pausing (with ctrl–z, as offered above) does the trick.

So the recipe is:

1. ctrl–c (does nothing right away)
2. ctrl–z (pauses WEBrick, goes back to shell)

3. fg (resumes WEBrick, immediately follow through with SIGINT)
