If anyone is interested in looking at a signal problem in top, here's a small but annoying bug..
- run top in an xterm - resize the window - try to use an interactive command that takes an argument, e.g. "s" or "g" (doesn't happen with commands like "S" or "H" that work immediately) Often, pressing the command key just refreshes the screen, it takes multiple attempts for the command to take effect (sometimes just a couple, sometimes loads of attempts).
