Destroys a writable stream if a write ever hits the high water mark.
This is useful when piping a single stream to multiple clients -
you don't want one client slowing down the rest of the clients.
With how streams currently work, streams flow at the speed of the slowest destination stream.
``js
var Stream = require('stream');
var destroyOnHWM = require('destroy-on-hwm');
var stream = new Stream.PassThrough();
/**
* With no callback, attempts to execute stream.destroy() on high water mark..destroy()
* This stream does not have though, so it's really a noop.
*/
destroyOnHWM(stream);
/**
* Instead, we'll just use a custom callback.
*/
destroyOnHWM(stream, function (stream) {
assert(stream === this); // the stream is passed as both this and the first argument``
console.log('High water mark reached!');
});
