[TuxOnIce-users] small heads-up: ToI write speed really low again

[Nix]

Since 2.6.35, no_flusher_thread 0 has caused a hard lockup on my 4-way
hyperthreaded Core i7 (the same one you did the speedup work on last
time). Unfortunately no_flusher_thread 1 is slower than ever:

Sometimes I see write speed as low as 40Mb/s :(
