8 byte signed integer -1, accidentally printed as unsigned value.  I
fixed that in CVS.  Write returned -1 here because the pipe write
returned an error code 233, ERROR_PIPE_NOT_CONNECTED.  It looks like the
client process died for some reason.  This reason is not visible in the
output of cygserver, of course.
