+Subject: [PATCH] Ensure xcb owns socket and no other threads are writing
+ before send_request
+
+send_request may only write to out.queue if no other thread is busy
+writing to the network (as that thread may be writing from out.queue).
+
+send_request may only allocate request sequence numbers if XCB owns
+the socket.
+
+Therefore, send_request must make sure that both conditions are true
+when it holds iolock, which can only be done by looping until both
+conditions are true without having dropped the lock waiting for the
+second condition.
+
+We choose to get the socket back from Xlib first as get_socket_back
+has a complicated test and checking for other threads writing is a
+simple in-lined check.
+
+This also changes the sequence number checks (64k requests with no
+reply, 4M request wrapping) to ensure that both conditions are true
+before queueing the request.

+Subject: Force XCB event structures with 64-bit extended fields to be packed.
+
+With the advent of the Present extension, some events (such as
+PresentCompleteNotify) now use native 64-bit types on the wire.
+
+For XGE events, we insert an extra "uint32_t full_sequence" field
+immediately after the first 32 bytes of data.  Normally, this causes
+the subsequent fields to be shifted over by 4 bytes, and the structure
+to grow in size by 4 bytes.  Everything works fine.
+
+However, if event contains 64-bit extended fields, this may result in
+the compiler adding an extra 4 bytes of padding so that those fields
+remain aligned on 64-bit boundaries.  This causes the structure to grow
+by 8 bytes, not 4.  Unfortunately, XCB doesn't realize this, and
+always believes that the length only increased by 4.  read_packet()
+then fails to malloc enough memory to hold the event, and the event
+processing code uses the wrong offsets.
+
+To fix this, mark any event structures containing 64-bit extended
+fields with __attribute__((__packed__)).
+
+v2: Use any(...) instead of True in (...), as suggested by
+    Daniel Martin.
+
+v3 (Alan Coopersmith): Fix build with Solaris Studio 12.3 by moving the
+attribute to after the structure definition.
