strace output led me to starting syslog to see what gnome-keyring-daemon
was complaining about.  I'm seeing this:

Dec  3 16:22:55 norton gnome-keyring-daemon: PID 1136: couldn't set environment variable in session: The name org.gnome.SessionManager was not provided by any .service files

Dec  3 16:22:59 norton gnome-keyring-daemon: PID 1136: gku_prompt_get_response: assertion `self->pv->output' failed

According to strace, the "couldn't allocate secure memory..." messages
seems to be caused by this:

gnome-keyring-daemon 3820 seterrno_from_nt_status: /cygnus/src/uberbaum/winsup/cygwin/mmap.cc:1399 status 0xC0000061

That is coming from mlock() which hasn't changed in months.

The status above translates to: STATUS_PRIVILEGE_NOT_HELD and that is
coming from NtLockVirtualMemory() .

Yaakov or Corinna does any of the above mean anything to you?
