Files, unliking, access, oh my.

[Ken D'Ambrosio]

Hey, all.  For various esoteric reasons, I'm wondering if someone can 
tell me the answer to this question.

If process A is reading from a file, and process B deletes it, process 
A can continue to read from it until... well, until it stops reading 
from it.  Can that space that the file takes up be overwritten during 
this interim?  Or does the OS hold the inode sacrosanct until both 
references AND processes are no longer making use of it?

Or is it something else entirely, and I'm going down the wrong road?

Thanks!

-Ken
