Not tested but it's likely the leak is not in the Python interface

 (i)  the leak disappears when switching to UMFPACK
 (ii) the interaction with MUMPS happens on the C++ side

Status in DOLFIN: Fix Committed

Bug description:
There appear to be some small leaks in the Python interface. It could be related to FFC and/or Instant caching. Some test cases have been placed in 

  lp:~dolfin-core/dolfin/sandbox

in the 'memest' directory. These tests, and any new memory tests, should pass before a new release is made.
