This is the output from ipcs process startup where Cygwin fetches
all token info.  ipcs is fetching its own logon SID which is
always translated into the above group entry with gid 4095.

Cygserver is running as service here and is not part of that
session, so it doesn't know the login SID.  However, the code
inside pwdgrp::fetch_account_from_windows should translate this
into

  line: <OtherSession:S-1-5-5-0-82109179:4094:>

But even if that doesn't work as desired, it doesn't explain the 5secs
delay on these machines.  I don't se any clue here, sorry.
