I can drop the check.  With the Linux VFS layer, it is difficult to tell
whether this condition can ever happen, and if it does, we would likely
enter an infinite loop without the check.

Tradition has it that it's a replacement for the ENOSPC condition, and that would be sticky and happen again in the next loop iteration. 

Thanks,
