Added code to the scheduler so that it will dump core on SEGV. This 

is disabled by default.  Having this
is really useful if the scheduler is crashing some of the time.  You
can load the core dump file into a debugger to see where things are
breaking.  To use this, edit sched/main.C by hand and set
#define DUMP_CORE_ON_SEGV 1
