for this amount of seconds (default: 75) when a server splits.
This helps in case a server dies and the clients reconnect to the
other servers, causing a join-flood to be triggered needlessly.
Of course, OTOH disabling a flood protection temporarily is not
ideal, but after seeing it being triggered too often and requiring
manual intervention in many +f/+F channels, this is the best option
I think, if we want +f/+F to work as painless as possible.
If you have a large network (eg: >5 servers) with equal user
spreading then you could disable this by setting it to 0, since then
1 server dieing may not have enough impact on +f join floods
for this to be needed.
