Bug 1174770 has been filed to investigate a tpaint regression for e10s, and we've isolated the slow path to just the one taken when the user creates a new window (and presumably if they create a new tab *) going through ContentParent::RecvCreateWindow.

We want to know how often that slow path is hit. This bug is about adding a Telemetry probe to try to gather that information.
