CarpetLib: Output memory statistics, and limit maximum memory usage
Introduce a new parameter print_memstats_every. When non-zero, output the current and total allocated amount of memory (per process). Introduce a new parameter max_allowed_memory_MB. When more than that amount should be allocated on the current processor, abort the run. Only memory for grid variables counts; memory for administrative overhead is ignored. darcs-hash:20050727201851-891bb-c1ff9fc30ff949d576d500fbf70ad7fb5084836a.gz
