avoid multiple ikiwiki cgi processes piling up, eating all memory, and thrashing
Fixed by making the cgi wrapper wait on a cgilock. If you had to set apache's MaxClients low to avoid ikiwiki thrashing your server, you can now turn it up to a high value. The downside to this is that a cgi call that doesn't need to call lockwiki will be serialised by this so only one can run at a time. (For example, do=search.) There are few such calls, and all of them call loadindex, so each still eats gobs of memory, so serialising them still seems ok.
