Disable session_grace for now.

It is not clear if this is a benefit or not.  There seems to be a significant
(100msec ?) inter-request gap and seeting the grace period that long
means tying up worker threads doing basically nothing.

Setting a short timeout (10msec) results in an extra system call which
practically never does anything good.

Unless benefit is shown, this stuff should be removed again.
