to a large extent this is true. its not 100%, but the extent of Ingo's
work would be dramatically reduced for a low latency patch for 2.4
compared to 2.2. I have used 2.3.51, for example, with 3ms latency,
and got results almost as good as 2.2.10+LL.

I'm there, all the time, but until the VM guys get close to fixing up
the VM/cache system so that streaming I/O is close to usable again,
I'm keeping my mouth shut for now. 2.3.51 could record 24 tracks of 32
bit audio to a single disk without breaking a sweat. the stupidly
named 2.4.0-test1-ac* series can't do more than 6-8 without falling
over itself.
