Follow-up Comment #1:
Surprisingly this slowdown is still present on the development branch. One
doesn't even need the for loop to see that the slowdown is ~75X.
octave:15> clear all
octave:16> x = 1
x = 1
octave:17> tic; exist ("x", "var"); toc

octave:18> tic; exist ("y", "var"); toc
Elapsed time is 0.019058 seconds.
