Good catch. Bringing lines 39-41 in the if i==0 block makes the label texts
appear jagged. See my output for this case at ->
http://atmos.uwyo.edu/~gsever/data/matplotlib/test_speed3_jaggedlabels.pdf

Putting these lines right below main fig and grid object creations make
them look normal, and this case saves me 3-5 more seconds.

Setting share_all option to 1 makes x-ticks unreasonably placed on the
axes. As if the share_all option is applied only to the first plot call.
See the example output at ->
http://atmos.uwyo.edu/~gsever/data/matplotlib/test_speed3_badxaxes.pdf

I actually started with share_all=1 from this example ->
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/examples/demo_axes_grid.py
Particularly the construction given in def demo_grid_with_single_cbar(fig).
However I noticed, this behavior earlier and explicit grid calls solved
this issue.
