Distributed Automation kill()

Ok, so Ive been stumped by this problem for the last 3 days, and my exploration is reaching its limitations...

The key idea is that at any moment in time, the automation controller could theoretically have any number of threads open to any number of node machines running any number of applications in any number of parallel/serial combinations. Upon client error, it is EASY to stop any further commands from being sent, but this still theoretically leaves all the current commands untouched. Short from sending a reboot command to every node, is there some way I can force-stop the execution of anything that was effectively started by the controller (children, grand-children, etc)?

Any ideas?

XML::Stream::Node(3)					User Contributed Perl Documentation				      XML::Stream::Node(3)

NAME
XML::Stream::Node - Functions to make building and parsing the tree easier to work with. SYNOPSIS
Just a collection of functions that do not need to be in memory if you choose one of the other methods of data storage. This creates a hierarchy of Perl objects and provides various methods to manipulate the structure of the tree. It is much like the C library libxml. FORMAT
The result of parsing: <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo> would be: [ tag: foo att: {} children: [ tag: head att: {id=>"a"} children: [ tag: "__xmlstream__:node:cdata" children: "Hello " ] [ tag: em children: [ tag: "__xmlstream__:node:cdata" children: "there" ] ] ] [ tag: bar children: [ tag: "__xmlstream__:node:cdata" children: "Howdy " ] [ tag: ref ] ] [ tag: "__xmlstream__:node:cdata" children: "do" ] ] METHODS
new() - creates a new node. If you specify tag, then the root new(tag) tag is set. If you specify data, then cdata is added new(tag,cdata) to the node as well. Returns the created node. get_tag() - returns the root tag of the node. set_tag(tag) - set the root tag of the node to tag. add_child(node) - adds the specified node as a child to the current add_child(tag) node, or creates a new node with the specified tag add_child(tag,cdata) as the root node. Returns the node added. remove_child(node) - removes the child node from the current node. remove_cdata() - removes all of the cdata children from the current node. add_cdata(string) - adds the string as cdata onto the current nodes child list. get_cdata() - returns all of the cdata children concatenated together into one string. get_attrib(attrib) - returns the value of the attrib if it is valid, or returns undef is attrib is not a real attribute. put_attrib(hash) - for each key/value pair specified, create an attribute in the node. remove_attrib(attrib) - remove the specified attribute from the node. add_raw_xml(string,[string,...]) - directly add a string into the XML packet as the last child, with no translation. get_raw_xml() - return all of the XML in a single string, undef if there is no raw XML to include. remove_raw_xml() - remove all raw XML strings. children() - return all of the children of the node in a list. attrib() - returns a hash containing all of the attributes on this node. copy() - return a recursive copy of the node. XPath(path) - run XML::Stream::XPath on this node. XPathCheck(path) - run XML::Stream::XPath on this node and return 1 or 0 to see if it matches or not. GetXML() - return the node in XML string form.
