No. Binary runs from these blocks. Maybe you can force it to run from swap by modifying these pages through ptrace interface, but it is not supported. Just kill the app if you need these blocks. > From what I understand, the inode is not released until the program > ends. Do all the file-systems behave the same way ? No. Some will refuse to unlink running app (or another opened file). Some will unlink it immediately, and app then dies when it needs page-in something. Some works as POSIX mandates.
