In my experiments with real-time audio signal processing I could always
find a culprit for buffer-underflows other than the garbage collector.
Sometimes it was a space leak (e.g. by adding a finalizer to the wrong
object), sometimes incorrect handling of time differences, and when
working with LLVM it was frequent recompilation of LLVM code.
