tp: workaround traces with massively out-of-order events

This CL works around extremely slow loading of write_into_file
traces which have events very much out of order (i.e. not
respecting flush_period_ms).

This allows these traces to be opened though much of the data inside
these traces will be dropped as being out of order.
