35MB of memory is too large to expose amap leakage, since most of the amaps
are associated with single pages. The X server does some very large
allocations,
and thus SIZE will not show these very well.
To see the problem, It is better to look at "UVM amap" in "vmstat -m"
UVM amap 32835 1690K 2636K 78644K 26812908 0
16,32,64,128,256,512,1024,4096,8192
^^^^ this number is way too big, it should be 500 to 2000 ish.
