There was one fix applied to CVS affecting one of the memory alignment
macros for the AMD64 platform, reminds me that I need to make another
release of FluidSynth at some point soon.  I had planned on implementing
some other things before then (improved tunable voice stealing), but
that just hasn't happened yet.  So you may want to give CVS a try.
Don't use SSE either, its probably broken in FluidSynth and I don't
think has much of a performance increase currently.

Means that FluidSynth wasn't able to memory lock the SoundFont which
could lead to it getting swapped to virtual memory (hard disk).  Not a
major issue, but can lead to audio dropouts and other artifacts if a
note is played for which the sample data has to be loaded from disk.
Running as root would allow FluidSynth to lock its memory.
