So you noticed :) I sent a similar email to the list about a week and a
half ago, hope you got it (since this list hasn't been treating me all
that good):

I think another version of FluidSynth should be released soon. It makes
me sad to think someone might be trying out FluidSynth for the first
time only to find it takes up 100% CPU and doesn't run SCHED_FIFO (I
guess thats a good thing considering the previous problem :) so audio
glitches run rampant. I would hope these users have some patience and
don't go away just because of this first impression. Since it really is
an excellent synth.

Of course my copy has been fixed, so I tend to forget what the public is
using. I have been happily jamming with various people. Its been really
cool and I now have a nice expression pedal that I can use with my
keyboard to map various effects to. Which reminds me, I should release
another version of Swami, since I fixed lots of bugs concerning the
global modulators and added some new features too. Cheers.
