changing firewall state temporarily halt network completely.

I've noticed that when re-setting my firewall with a new set of rules, all network communication completely stops for a short time, until it regains with the new set of rules.

In fact, it also occurs when I start firewall after it was previously closed or when it switch from enable to disable state.

Why does PacketFiler temporarily halt connection every time it changes state (using pfctl -Ef or pfctl -d) ?
