+David  29 July 2009
+    - scheduler: on second thought, it would be better to add the above
+        feature without requiring use of score-based scheduling.
+        So add a new customizable function, wu_is_infeasible_custom(),
+        where projects can put job-specific checks.
+
+        Also, move customizable functions (of which there are now 4)
+        to a new file, sched_customize.cpp.
