+Subject: [PATCH 1/1] eigen/test.c: loosen tolerance in eigenvalue norm tests
+
+One test for the (unit) norm of a random hermitian matrix's
+eigenvalues is victim to tolerance issues, e.g.
+
+  FAIL: herm random, normalized(1), unsorted (0.999999999999999112
+  observed vs 1 expected) [117761]
+
+The tolerance used is N*GSL_DBL_EPSILON, where N is the size of the
+matrix. On my machine, the actual error is four times GSL_DBL_EPSILON,
+which means that the tolernace is close but not quite right. Despite
+having done a PhD in numerical analysis, I am choosing to fix this
+with a shotgun:
+
+  * By a factor of 10
+  * Then also by a factor of N
+
+That's still extremely close, and hopefully will sweep the problem
+under the rug whether it's off by a constant or off by a function
+of N.
