* Up to 11kHz persistent on my home machine. Still a little way off the 13kHz ↵Matthew Sackman2009-12-022-30/+106
| | | | that I was getting before, but there were bugs in the previous QI (eg missing syncs) which could well have led to the old version being too fast. Added two functions to fhc: delete/1 which deletes without flushing any data at all. It will refuse to delete if the file isn't open; discard_write_buffer/1 which does what it says. We use the latter after scattering the journal as after we hit each segment, we sync the segment, so at that point there's no need at all to force out the data in the fhc for the journal prior to truncation.
* Allowed the journal to grow substantially bigger. This helps performance ↵Matthew Sackman2009-12-021-1/+1

* New qi in place, tested and debugged. It works. It's not quite as fast as ↵Matthew Sackman2009-12-024-1460/+594
| | | | before because of use of nested dicts. This can be solved by using sets for publishes, deliveries and acks within each segment - we don't actually need what the dict provides and sets will go much faster. That change should be fairly straight forward to do - the code will get a little longer, but not much more complex.

* There was a bug. Now it has gone away. It arose when γ has a partial ↵Matthew Sackman2009-11-273-39/+116
| | | | segment, and then memory is made available, and the next msg is persistent. It will go into the partial segment in qi, but will also be in q1 in vq. This lead to the msg being duplicated. Solution is to track the max seq id beyond the end of the γs, and thus drop anything being returned in the segment from qi with a seq_id above this max seq id.
