deleting text in FRED windows

["Roland Zito-Wolf" <rjz@chaos.cs.brandeis.edu>]

IS there a way to delete text so that the memory it occupies
is guaranteed to be reclaimed, ie, to delete it WITHOUT putting it
on the kill ring or adding an UNDO entry for it (and preferebly, 
not putting it in the Clipboard either)? 

Though its not my preferred method, I assume that deleting a window
DOES delete its contents irretrievably.

thanks,
