I've been poking around with IOS trying to write a section of
code which delete a file after it has been processed. It seems
that I must have the file open for write-access before calling
IOS_$DELETE, but I can't always set write access since another
process may have the file open for reading. Can anyone give me
a pointer on how to implement a delete-when-unlocked feature
similar to the -DU option of DLF? I've tried using 
IOS_$SET_OBJ_FLAG to set the delete-on-close flag, but that
also seems to require that the file be opened for writing.
