When I said "10s seems very conservative", I meant, "10s should be by
far long enough for something to happen".  If you can't free up at least
1k in 30s, then there is certainly something very unusual with your
system.  So I was recommending leaving that the default.

I'm not really sure under what conditions an admin might want to fiddle
with the timeout, however, so I'm having second thoughts about adding
new options.
