Thanks for the patch.


+ case 'L':
+     LoadAverage = atoi(optarg);
+     break;

+ if (LoadAverage) {
+     double loadavg;
+     while (getloadavg(&loadavg, 1) > 0 && (int)loadavg >= LoadAverage) {
+         sleep(1);
+     }
+ }


To INN maintainers:
Should we use "makehistory -L <number>" or a new makehistoryloadlimit:
parameter in inn.conf (based upon the existing nnrpdloadlimit: one)?
What would be the default value?  16 like nnrpd?  or 0 for no limit?

Is it okay to use "sleep(1)" like this?

(Is there something to do for makedbz, expire, expireover..?  I do not
know whether it is wise to make them sleep -- they could take a very long
time to execute and we would have to find the right moment to put the sleep.)
