It's doesn't create users.
It only drops privileges (extremesetuidgid) or sets $UID/$GID env. variables (extremeenvuidgid).

For example:
extremesetuidgid -b 100000 sleep 1

runs command 'sleep 1' under unprivileged uid/gid (computed getpid() +100000) 
e.g. for:
pid=10 ... uid=gid=100010
pid=11 ... uid=gid=100011
pid=12 ... uid=gid=100011
...
