Corrected some larger read/write issues in corner cases that I hit suprisingly

often within nids.  There's still a problem somewhere, but I'll find it.

Also, even after having the file class canRead and canWrite functions work
properly, and using them before trying to write to a nids to update info, we
never ever write anything, so something is still wrong there.  For now, all
utilities that open a nids stream read-only will crash when it closes.  Pretty
minor really.
