relatedly, i call "`eval resize`" in my .zshrc--any idea why that takes ~5s if it's more than a minute or two since i last did it, but is instantaneous otherwise? (yes, i'm certain that it's that line that's taking time--if i start typing during the delay before the prompt shows up, i get a resize error about unrecognized characters and then a couple bits of random ANSI on my input.)
