PyPlot figures unresponsive

[mweastwood]

In the past couple of days, I noticed a weird problem with PyPlot:

using PyPlot
figure(1) # Nothing happens
figure(2) # Figure 1 shows up, but Figure 2 is nowhere to be seen
close(1) # Figure 1 closes as expected, but now Figure 2 shows up

Furthermore, the figure windows are unresponsive. It is possible to update what is displayed within them by opening and closing an unrelated figure, but you can't pan or zoom within the figure itself.

I ran git bisect to locate the issue and I find

The second argument (status) to timer callbacks never did anything, and is now removed. Packages that use timers will need to remove this argument.

Docs updated and change announced.

@JeffBezanson, is there any way we could make this break more noisily, i.e. throw an exception?
