What really bugs me with traverse checking is, that I don't have any
problems with it on the machines I'm using.

Looks pretty sufficient.  Are the permissions also sufficient for
/etc, /etc/passwd and /etc/group?

If you're interested to debug this further, you could do me two favors.

- With traverse not switched off (don't set CYGWIN=notraverse), please run
    strace -o id.strace -m 4ffff id
  and
    strace -o bash.strace -m 4ffff bash --login 

  When creating the bash strace, run any one command which is expected to
  fail with "fork: Permission denied" so that this situation is catched
  in the strace output.

  Send both straces bzip2'd to this list.

- Try the latest snapshot from http://cygwin.com/snapshots/ and report if
  the problem persists.


Thanks,
Corinna
