Code to use ctrl-break to get a java stack dump

[Timothy Wall <twall at users dot sourceforge dot net>]

Since cygwin will kill a subprocess if you hit ctrl-break manually, 
I've written a little utility that allows you to send ctrl-break 
directly to the java process from any other console on the same 
machine.

Note that if java is invoked directly from the shell, cygwin gets the 
ctrl-break and still kills java, but I usually run my java invocations 
from a makefile target, which somehow allows this to work.

e.g.

test:
	if  /bin/true; then java -cp . MyClass; fi


make test

Then, from some other console:

./cbreak

Hopefully someone else will find this of use.  The process walking code 
was taken from some gnarly MS example;  I'm sure there's got to be a 
better way.  This probably only works on XP and later (haven't tried it 
elsewhere, but some of the system calls used are marked XP+ only).
