Breadth-first globbing is **/*(/Od)
but in this case the problem is that globbing itself can't match anything
until the directory modes have changed, I think?

So I'd just do something like

while chmod +x **/*(/^x); do :; done

Assuming you have nomatch set so the loop will fail when all directories
have the x mode.
