Still no joy, see attached kmemleak output. In about four hours time,  
free memory decreased by about 10% (of 128 MB). Is there anything else  
I can do to aid in finding the cause? This is with r47953 by the way,  
with the above mentioned patch included (I checked in the build_dir,  
the patch applied successfully.

Best regards,
