The protocol document simply says that "[t]he window and all inferiors
are [...] destroyed".  As far as I can see, nowhere does it explicitly
say that destroying a window frees the ID of that window for reuse,
though it seems to me that it's rather too obvious to need saying.

Root windows can't be destroyed.
