I think it would be handy to be able to summirize wait events by event
names, instead of classes. In other words, grouping wait events
through all classes according to their purpose. From that perspective,
I'm rather fan of consolidating event names (that is, the opposite of
your proposal).

However, it seems the event weren't named with this consideration. So
I'm on the fence about this change.

By the way, I couldn't figure out how to tag event names without
messing up the source tree. This causes meson to refuse a build..

regards.
