D'oh.  Wonder how often we will keep encountering this.

I have not understood what's going on here.  Are these files running
concurrently in the same pwd?

No.  The issue is different.  Whenever you have
 $program > file

and $program itself spawns other processes which inherit the file
descriptor to 'file', and write to it concurrently, then POSIX does
not guarantee that those writes are atomic.

Thanks, it is cristal clear now!
