I'm running a test with daqd right now, so please do not disturb for the moment.

I'm temporarily writing frames into a tempfs, which is a filesystem that exists purely in memory.  There should be ZERO IO contention for this filesystem, so if the daqd failures are due to IO then all problems should disappear.  If they don't, then we're dealing with some other problem.

There will be no data saved during this period.
