#3096: zooming to home view no longer zooms, seems to block

 This is a performance bug.  The new addition of activity memory size
 parsing causes the call to zoom to the home view to take roughly .5
 seconds in which we block and I am guessing the animation gives up and
 goes to the last frame making it look like it just jumps instead of
 smoothly transitioning.

 The culprit is parse_smaps_size_line which is called 3801 times.  If this
 is needed I suggest doing this in a background thread and updating only
 when new processes run.  The display does not need to be updated in real
 time but only needs to give an approximation of memory usage.  I would
 suggest the update only happens when activities are run and perhaps after
 a timeout when other processes are run to avoid draining the battery from
 someone running grep or similar short lived programs.
