Possibly I'm being dozy but this is the first thing I've heard that
sounds like a robust fix, if it's the case that we always find an
appropriate running process in the case that was causing the original

I don't think efficiency is a problem.  zsh makes no attempt to ensure
the process you're actually looking for is found quickly in any case.
If it is a problem, surely that means the process search is
intrinsically inefficient and we need to do something more basic about
it such as putting the processes in a hash table, or whatever.  Generally,
I suspect it's rare for the shell to have enough processes to make the
time is important, and if it is important this change is a minor
effect.  Of course, if anyone wants to profile it they're welcome.
