This sounds very strange.  Why would the failure depend on the size of
the file/directory and on whether it does or doesn't cross
filesystems?  I see nothing in the code involved in this that could
cause that.  Perhaps on your system something happens in the
background, due to one of the filesystems being encrypted or
something?
