I've been trying to use the Random String Parameter plugin to avoid missing changes in a Git SCM. I'm using SCM polling to identify changes, but it seems that this can cause multiple identical builds to be triggered if the build queue is long enough, and because the parameter is random all of these duplicate builds will be run.

If there was some way to make the string based on the trigger reason it would queue up builds but prevent this duplication of builds. Perhaps this would be best as a separate plugin, but this one is so close to what I need that I thought it might be worth considering this as an enhancement.
