This looks like the same problem as [1] (you are using zsh, right?).
You should be able to work around it by passing the "-f" flag (please
confirm), or by not using zsh.  (No, I don't think they are viable
alternatives, but it's all I have at the moment.)

I debugged the problem and found that it is caused by calling setsid()
when forking but have no idea why this is [2].  It is called from
macos_fork() inside src/os_macosx.m in case you feel like debugging
the issue.  I'd appreciate the help -- I'm not getting anywhere with
it.
