Windows does the right thing. Files shouldn't be pulled out from under running applications without warning.

A less privileged executable has no say on what i do to its files (or itself). One time, while ssh'd into a box, i created a directory with some basic stuff and chroot'd into it and then deleted the entire host OS (redhat). Ssh continued to function and kept my connection alive even though its own executable didn't exist anymore. From my small chroot environment i installed a completely different distro (Gentoo) where the old root was. Built and installed a new kernel. Crossed fingers and rebooted the machine (it worked!). That's the kind of admin powers you get with a real OS. Your reasoning is exactly why you cannot delete windows malware without restarting into safe mode.

And they are not.
What happens is that their entry in the FS is removed, but as long as the program keeps the file open they have a entry to it.
Flash tries to use this to hide their streaming caches on Linux.
Fire up any video steam, then head for /proc/"flash pid"/fd, if you do a ls -l you will see symlink that points to a file in /tmp that has already been deleted. But as the flash process still has it as open, it can still read and write to it all it wants. but once it lets go, it is gone, unless you go at the FS with a recovery utility.
