Re: [PATCH] Remove atomic operations from malloc.c


I did get into the changes itself, but at least for powerpc (POWER8/16c/128T)
I am not seeing improvements with the patch.  In fact it seems to increase
contention:

            time per iteration
nths       master     patch
1    	   51.422    75.046
8          53.077    78.507
16         57.430    89.385
32         71.206   108.359
64        114.370   172.115
128       251.731   330.924


Thank you for testing! Maybe the costs of a mutex_lock are higher on PowerPC than on i686? Anyway it looks like I have to take a different approach...
