#1891: Segv in xerbla if called by QR routines
--------------------------+-------------------------------------------------
 Reporter:  pv            |       Owner:  pv         
     Type:  defect        |      Status:  new        
 Priority:  normal        |   Milestone:  Unscheduled
Component:  scipy.linalg  |     Version:  0.12.0     
 Keywords:                |  
--------------------------+-------------------------------------------------
 Since some of the QR routines in flapackf.pyf.src are marked as
 threadsafe, and python_xerbla.c inside Numpy assumes it has GIL, if xerbla
 is called by LAPACK to report an error, a segfault ensues.
