Sorry, the backtraces were actually useful because they show that you
are apparently running cygwin-snapshot-20130107.  Apparently you haven't
been watching the discussion about this issue in the Cygwin list.  The
problem of a Cygwin process hanging after a single CTRL-C should be
fixed in later snapshots although there is another reported CTRL-C
issue.
