Er, I think this is a very unlikely statement... removeItem is used
extensively throughout the code, and if it didn't work in IE6, we'd have
a lot of trouble. 

I've just confirmed via Firebug Lite in IE that
OpenLayers.Util.removeItem(['1','2','3'], '2')

returns:

['1', '3']

So, I don't think looking at OpenLayers.Util.removeItem askance is
likely to work well.
