Never mind that, I could easily reproduce the issue.  Please try the
latest snapshot from http://cygwin.com/snapshots/.  It's supposed to fix
this issue.  It also introduces another new behaviour as outlined in

  http://cygwin.com/ml/cygwin/2014-02/msg00735.html

Note that "db_cache: full" is the default for now so the new feature
gets a bit more testing.  The former default would have been equivalent
to "db_cache: yes".


Thanks,
Corinna
