Replying to [comment:2 jackburton]:
> In theory "waitpid(-1, &status, WNOHANG)" should tell if a child process
has exited or not, and thus be used to tell if a program is still running.
In practice, I've experimented with it a bit, but there seems to be no
difference in the returned values.
> Maybe since "bash" is already a child process, waitpid() will always
return that there are still child processes runing.
Maybe I misunderstand what you're saying. waitpid() does not tell you
whether there are still living children. It does only tell you about
terminated children. I don't see what this has to do with this ticket,
though. Isn't this just about checking whether number of tabs > 1 before
quitting?
