[Sugar-devel] Record and Journal problem

[Erik Blankinship]

Discussion about preventing recordings when the journal is "near full" can

I am not sure if there is a suggested Sugar api call nowadays to determine
if there is "enough space".   It would be great if there was.  We want to be
sure to to pay attention to JG's warning (from #4983):

Please, have oggenc fail significantly *before* filling flash. Similarly for
the camera app itself. The system has to work harder and harder on GC as the
free space drops.

You can adjust the threshold in Record by changing the variable
keepFreeKbOnXo in constants.py

show up as 2637-4737-13323-dl77nf, or some such gibberish. Here's how to
figure it out.
