Usage of XGetAsyncReply with discard == True in Xlib are:

XGetWindowAttributes(): Nothing to discard
XInternAtom(): Nothing to discard
QueryExtension (from XOpenDisplay): nothing to discard

It only affects the case when you are actually discarding
something, and the XIOError case where the server sends back a 
too short reply. I noticed this because I accidentally passed True 
for GetProperty and corrupted the protocol stream
in a way I didn't expect.

I expect passing discard=True in a case where it matters is rare
for both _XReply and _XGetAsyncReply.
