Patch adding a check of the result of the allocation of stats

Calling ab (the Apache benchmark utility) with the argument -n 1234567890 http://example.org (or any -n other value smaller than MAXINT, but bigger than the virtual memory divided by 32) causes ab to segfault. This is a result of using a dynamically allocated data structure(line ~1260) whose allocation(line 1559) is not checked. The size of this data structure is linearly dependent of the -n value. This may be a design bug in itself since it prevents ab runs with a potentially infinite number of requests, e.g. to test how many requests can be served in 42 seconds. The attached patch makes ab exit properly when the memory allocation fails.
