[Matplotlib-devel] import time doubled by master vs 1.4.3

[Eric Firing]

test:

time python -c "from matplotlib import pyplot"

On a linux VM with Py 3.4 the user time is around

0.25 s for 1.4.3
0.5 s for master

That's quite a difference.  Can anyone else reproduce this?  Any ideas 
as to what is causing the slowdown?

In both tests the backend was tkagg, so the difference was not a matter 
of importing different gui toolkits.
