Two more interesting facts:
- When the bug is triggered, the clock stops updating in real-time and
instead seems to be refreshed every 4 or 5 seconds, jumping by that
about that amount.
- Ocasionally, eeven jackd needs to be restarted in order for ecasound
to work with jack again, suggesting some gremlins in the jack client
code as you mention.
