> 
> Currently, when using IPsec-mb 1.4+, the process ID is obtained for each job in
> a burst with a call to getpid().
> This system call uses too many CPU cycles, and is unnecessary per job.
> 
> Instead, set the process ID value per lcore.
> This is read when processing the burst, instead of per job.
