2nd part for faster object transfer between cpus:

Make it tunable by writing to /proc/slabinfo.

The patch is against 2.5.69-mm6, it applies to 2.5.69-bk12 with some 
offsets.

What do you think? The change breaks backward compatibility: previously 
/proc/slabinfo expected two numbers (batchcount, limit), now it expects 
three numbers (batchcount, limit, sharedfactor). Calls with the wrong 
number of arguments just fail.
