While those commits themselves could be useful even if they don't
completely fix #299, they come with the risks of introduce more
unforeseen bugs, which outweigh their benefit, so revert them.

A brief explanation of their problem:

The fix hinges on the destroy event of the client window to work.
However, the client window could be destroyed so fast, before we even
handle the map, or even the create, event of the frame. And we won't be
listening for substructure events on the frame at the point the client
window is destroyed. Thus completely miss the client window destroy
event.

Because of the inherent racy nature of Xorg, this approach is really
difficult to make work.

Fixes #371
