+Author: Fabian Fagerholm <fabbe@debian.org>
+Description: Make sasl_set_alloc a one-time function.
+This patch will divert all allocations to whomever called
+sasl_set_alloc first, hopefully that will be the application. If
+not, we sure *hope* the library doing stupid things has sane
+sasl_set_alloc semantics...
+It will also deny any futher tries to sasl_set_alloc after one
+of the _init functions are called.
+This patch was introduced and works fine in SASL 1.5, and no
+applications started behaving in insane ways, so chances are it
+will also work with SASL 2.1
