In MOD05 processing, calculating cover with perimeter sometimes hangs

[captainkirk99]

The first file is processed in 40 seconds, the second file is hanging.

Note the difference in the cover settings, in particular pk = -1 in the first case, 1347 in the case that hangs.

@michaelleerilee I believe you wrote the cover code - do you know what is going on? The code is here:
