Polling at 100Hz is a horrendous solution from a technical point of view.
I typical have a dozen IPython instances opened, where I have been
working a while ago, but not doing anything right now, because I am
planning to come back to it. Having these all poll at a 100Hz wil keep my
laptop hot, make it switch context all the time, and drain the battery.
Adobe Flash works that way. I use it as seldom as possible.

One trick I play sometimes when I am developping software that needs to
poll and cannot be event-driven, is to unable polling when there is
activity, but turn it off when there is None. I am not sure how you can
adapt the idea here, though.
