Description Jamey Sharp 2006-06-11 01:12:21 UTC

When XCB reads the header of a response that turns out to be a >4kB reply, it
currently does one big read to get the rest of the reply, and then goes back to
doing another read to fill the input buffer. For a small optimization, it should
instead use readv to request both reads simultaneously.
