I played with this all day and I can't convince myself that it isn't a
readline bug.  It seems like there is a situation where bash/readline
unmasks SIGINT and potentially lets a stray CTRL-C in while the signal
handler is still carefully dealing with signals, causing recursion and,
eventually, an overflow of cygwin's signal stack.

In fact, I could crash bash on linux by doing a:

  while kill -INT nnn; do :; done

where nnn denotes the pid of a running Debian bash 3.00.16(1)-release

In any event, this isn't a regression and, unless I have an amazing
insight sometime soon, I don't think there is any way to fix this
in the cygwin DLL.
