* don't use kvm_* calls, just sysctl (so no suid perm necessary) * sysctls calls in general aren't thread safe, collapse callbacks using same sysctls (specifically total/running procs and proc list ones). Some sysctls need two calls (first to get size of obj returned, second to get object self); if different threads use this schema on same sysctl, weird values are returned (first/second calls sequence should be serialized). In general it makes not much sense too having more threads that use the same sysctl; just get info once and populate all data. * add DragonFly specific extended uname string ($version in conky.conf) with git version and signature Todo: - top process list logic is old style, use top.cc funcs. - find a solution for cpu freq Signed-off-by: Pavel Labath <pavelo@centrum.sk>
