Might one have problems truncating an open RW file if data is caught in the
buffer from a read?  You won't flush the buffer unless you a. close the FH
or, b. set $| for the FH.  I haven't checked, but stuff in the read buffer
might interfere with write operations...

I think I may try this... just because I'd like to add to my growing list
of informative but otherwise useless scripts.
