 I had some more crashes with irregular intervals. Two of them didn't
 leave a core dump; /var/log/messages listed errno 27 (EFBIG).
 The 4 core dumps I have are available for debugging.
 
 I tried running with a locally modified version of libdrm_radeon.so.0.0
 with logging added to bo_map() and some nearby functions in
 xsrc/external/mit/libdrm/dist/radeon/radeon_bo_gem.c (printf to stderr)
 but I don't see the expected output anywhere. I'm not sure if I'm not
 looking in the right place, the output is getting lost, or X simply
 never gets there (in which case I don't understand why).
