Status:   

Detection of invalid offsets could be an interesting proposition on 
32-bit systems which don't support large files.  Detection of rollover 
on a 32-bit integer may be a challenge to reliably implement. 
Sometimes the off_t type supports 2GB access while other times it 
supports terrabytes.  Hopefully the system libraries are reliable at 
reporting writes beyond what is supported.
