There really is no reason to use 72 characters instead of -say- 64. The
increase in security is marginal and if the side-effect of using 64 is
that it works with more filesystems than that is a Good Thing (TM). We
are not alone in this world as -say- Microsoft tends to think.
It's probably better to just get rid of the PID and use randomness
troughout the name than to use 72 characters. 64^6 vs. 2*(72^3) .
Cheers,
Jeroen
