Comment (by wnbell):

 One solution to this problem is to simply replace the current Python +
 Fortran implementations of the iterative solvers with pure Python
 implementations.  Another problem with the Fortran code is that it's not
 reentrant, as reported here:

 http://thread.gmane.org/gmane.comp.python.numeric.general/28026/focus=28039

 The (mostly) pure Python implementations in PyAMG are possible
 replacements:
