[RFC] pid randomness

[Pedro Venda (SYSADM)]

hi everyone,

I don't know if this has been discussed before... but I'd like to ask 
why isn't the pids randomized by default?

I mean, of course it's not required for normal functioning but it'd be 
nice to have a Kconfig option to make it happen.

The (newbie) way I see it, it'd not be hard to do... generate pid, check 
if it's unique, give pid to process. It could bring some minor security 
enhancements while taking a slight performance hit (seek & compare 
algorithm for used pids).

What are the pros and cons of this? What are your oppinions on this subjet?

regards,
pedro venda.
