if you work with 64 samples at 44100 Hz, the audio hardware will send
you an interrupt each 1.4 ms ... on modern operating systems, you have a
scheduler granularity from 1000 Hz, so depending on the dispatcher of
your os, a suspend/resume cycle can take up to 1ms ... 

basically, blocking synchronization and low-latency audio are mutual
exclusive ...
