Well, Linux has no 1 second guarantees either. At the suggestion of Matthias, I now have a programm that recycles the same PID in much less than 1 second.

But you're not doing an exec() here. See how big of a penalty exec() imposes.

Doesn't matter, because this PID-cycler process might run by ANYONE maliciously to attack Maildir-style programs.

Looks like using inodes instead of microseconds is going to be the final solution.

Yup. Postfix uses tmp/time.pid.host (believed safe) and renames to new/time.ino.host.
