oops, it did it again... (it's not that innocent )

i tried to catch this in a serial log, but the problem just didn't occur... but there are other things i see in the log that may be connected:

while the unit is playing, i see lines like these all the time:

spindown_chunk_cache_runner.cpp: 292:Filling up space (28)
spindown_chunk_cache_runner.cpp: 292:Filling up space (28)
spindown_chunk_cache_runner.cpp: 292:Filling up space (27)
spindown_chunk_cache_runner.cpp: 292:Filling up space (25)


and on startup i see these lines:

...
