I just want to avoid prejudices. Again, it won't take long til we have fixed 
those two issues, so I think it's worth waiting for it.

You'll see the problem in the Voice class, where the core synthesis is 
performed. I'm already on it. I wrote together with Vladimir MMX+SSE(1) 
Assembly Optimizations (the capability for MMX, SSE is detected at runtime), 
I also improved efficiency in looping and I'll fix other obvious efficiency 
issues like using the filter only if it's really needed and using the 
resampling algorithm only it's really needed. Hope to have this done in the 
next days for commiting.

Yeah, as we're currently more working on the efficiency, we have not yet 
looked deeply for the disk streaming bug. You'll face it when you have a big 
amount of voices which will lead to unavailable disk streams. But maybe this 
is linked with the bad efficiency, so that's why I decided to do these 
improvements first. Maybe if you have time to investigate, let us know if you 
find the reason for the disk streaming bug!
