See attached -- I was concerned that the separate XP namespaces could
affect Cygwin itself.  PostgreSQL's use of AF_UNIX sockets is the first
known case of this problem:

    $ handle -a -p postgres | fgrep secret
      364: Event \BaseNamedObjects\cygwin.local_socket.secret.54788.00000000-00000000-00000000-00000000

Thanks for bringing this to my attention.  I will work with the other
Cygwin developers to fix this problem and hopefully prevent others.

Does Cygwin itself need to be enhanced to support XP Fast User Switching
too?  See the following for the details:

    http://cygwin.com/ml/cygwin/2003-05/msg00282.html

While debugging the above, I noticed the following:

    $ handle -a -p mutt | fgrep '\BaseNamedObjects\cygwin'
       68: Section       \BaseNamedObjects\cygwin1S3.shared.3
       8c: Mutant        \BaseNamedObjects\cygwin1S3.title_mutex.0
       90: Section       \BaseNamedObjects\cygwin1S3.JATIS.27
       ac: Semaphore     \BaseNamedObjects\cygwin1S3.sigcatch.2128

Are there any Cygwin events, semaphores, etc. that can be similarly
affected by the multiple namespace issue too?
