I was able to create a small C-only testcase which shows the same
behaviour, its at: http://pastebin.com/f182de215
The interesting stuff starts at line 179, the protocol itself is
generated at 92 and following.

When resizing the window to trigger expose events, suddenly it stops
repainting and stucks e.g. at:
#0  0x00110416 in __kernel_vsyscall ()
#1  0x009885bd in ___newselect_nocancel () from /lib/libc.so.6
#2  0x00118035 in _xcb_conn_wait () from /opt/xorg/lib/libxcb.so.1
#3  0x0011a33a in xcb_wait_for_reply () from /opt/xorg/lib/libxcb.so.1
#4  0x00169078 in _XReply () from /opt/xorg/lib/libX11.so.6
#5  0x001627fb in _XPrivSyncFunction () from /opt/xorg/lib/libX11.so.6
#6  0x00242c42 in XRenderFillRectangle () from /opt/xorg/lib/libXrender.so.1
#7  0x08049115 in main ()

Thanks for your patience, Clemens
