About setuid in UNIX Sys V: any process that execs a setuid program file
can switch at will between the processes' real uid and the setuid of
the file. Thus, it can bounce between these two uid's as often as
necessary. This is an essentially undocumented feature os UNIX Sys V
(and derivatives, I hope).
