They are assigned linearly, however once a pid is used, it is never reused
until the machine reboots.
A pid of 413 means that when that process was fork()'ed there had been 412
other processes already created. But remember every time you type ls, you've
run a process.
413 isn't a large pid at all. My linux box which I very rarely reboot is at
PIDs that start at 20000
I'm surprised that any program you start after the boot process is as low as
412.
