net.server_epoll: Set minimum wait time to 1ms, matching epoll A timeout value less than 0.001 gets turned into zero on the C side, so epoll_wait() returns instantly and essentially busy-loops up to 1ms, e.g. when a timer event ends up scheduled (0, 0.001)ms into the future. Unsure if this has much effect in practice, but it may waste a small amount of CPU time. How much would depend on how often this ends up happening and how fast the CPU gets trough main loop iterations.
