[OpenSPIM] Software hangs during stack capture

Not that I am aware of, but there might be a lot of crap (updates, power manager, blabla…) that could interfere. I will see at cleaning this mess a bit.
However, I did not notice anything happening @ the GUI level and correlating with these hangs.

> I've been getting some weird hangings as each slice is written out (affecting the entire operating system, not just the SPIM software), but typically they were lasting no more than a half-second, and never on the order of minutes. They're recent, and I've been doing some timing tests to try and determine the cause to greater accuracy than 'when writing'.

Yep, internal HD.

Let's wait then.

With my best regards,
