This changes slightly the behavior of gitweb, so that it verifies that the box isn't inundated with before attempting to serve gitweb. If the box is overloaded, it basically returns a 503 Server Unavailable until the load falls below the defined threshold. This helps dramatically if you have a box that's I/O bound, reaches a certain load and you don't want gitweb, the I/O hog that it is, increasing the pain the server is already undergoing. This behavior is controlled by $maxload configuration variable. Default is a load of 300, which for most cases should never be hit. Unset it (set it to undefined value, i.e. undef) to turn off checking. Currently it requires that '/proc/loadavg' file exists, otherwise the load check is bypassed (load is taken to be 0). So platforms that do not implement '/proc/loadavg' currently cannot use this feature (provisions are included for additional checks to be added by others). There is simple test in t/t9501-gitweb-standalone-http-status.sh to check that it correctly returns "503 Service Unavailable" if load is too high, and also if there are any Perl warnings or errors.
