prefork => worker への「等価」変換

StartServers = StartServers(p) / ThreadsPerChild
MinSpareThreads = MinSpareServers(p)
MaxSpareThreads = MaxSpareServers(p)
ServerLimit = ServerLimit(p) / ThreadsPerChild
ThreadLimit = ThreadsPerChild
ThreadsPerChild = 1プロセスでいくつのスレッドを処理するか(これから試行)
MaxClients = MaxClients(p)
MaxRequestsPerChild = MaxRequestsPerChild(p) * ThreadsPerChild
MaxMemFree = MaxMemFree(p) * ThreadsPerChild
