Comment(by mwiebe):

 I can see it very clearly with the following procedure:

 1. Open Task Manager/System Monitor to see memory usage

 2. Run the following, which shows a jump upwards in memory usage.
 {{{
 >>> import numpy as np
 >>> a = np.zeros((10000,10000),dtype=np.float)
 }}}
 3. Run the following, which drops the memory usage back down in an older
 version of NumPy, but not in master.
 {{{
 >>> del a
 }}}
