[MonoTouch] Monotouch issue with Xcode's Instruments

[Rolf Bjarne Kvinge]

Hi,

I think you're looking only at the Live Bytes, but they don't tell the
whole story.

You need to look at the VM tracker tool, and take heap snapshots there.
Then you look at the heapshots, and in particular look at the Dirty Size
column and the Memory Tag 70 row (Memory Tag 70 is image data, which is
usually where issues are).

I hope this helps,
Rolf
