22 processes' pgid/sid enumerated as uid=1001 (no EPERM)
===
[parent] pid=920 pgid=918 sid=918 uid=1001

[parent] probing child pid=921 (DIFFERENT session):
  getpgid(921) = 921  errno=0 (Undefined error: 0)
  getsid(921)  = 921  errno=0 (Undefined error: 0)

BUG DF-0037 REPRODUCED: parent (sid=918) leaked child's pgid/sid from a DIFFERENT session with no EPERM.
  POSIX violation: getpgid/getsid on a process in another session MUST return EPERM.
