Using -ttt causes CVS to fail almost immediately:

   $ cvs -ttt -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/gnulib co 
gnulib
     -> main: Session ID is 2QdKzydInS61g6Nr
     -> parse_cvsroot (:pserver:anonymous@cvs.savannah.gnu.org:/sources/gnulib)
     -> walklist ( list=0x80fc900, proc=0x8078040, closure=(nil) )
     -> main loop with CVSROOT=/sources/gnulib
     -> safe_location( where=(null) )
     -> open_connection_to_server 
(:pserver:anonymous@cvs.savannah.gnu.org:/sources/gnulib)
     -> Connecting to cvs.savannah.gnu.org(199.232.41.69):2401.

The command

  CVS_CLIENT_LOG=cvs-client-log cvs -z3 
-d:pserver:anonymous@cvs.savannah.gnu.org:/sources/gnulib co gnulib

works fine; it does not hang.  I can still reproduce the original
problem, though, if I don't set CVS_CLIENT_LOG.

I take it that you were unable to reproduce the problem?  It is a bit
weird that the problem occurs for me on two quite-different platforms,
but it doesn't occur for you.

Perhaps it's because my network connection is faster?  It takes about
seven seconds real-time for the command "cvs -z3
-d:pserver:anonymous@cvs.savannah.gnu.org:/sources/gnulib co gnulib"
to work on my host, when I use CVS 1.12.9.
