It's odd that these fail because many/most virus scanners are written using file system filter drivers which operate in the IO stack, blocking CreateFile/open to scan the file, meaning most user processes don't even notice them (except for a very brief pause on CreateFile/open).

Running test suites under Windows 7
When I first installed Win7, I was having problems with erratic failures to write executable files while running the D test suite. Eventually, I discovered that Windows Defender was the problem, as it tried to do a virus can on every exe the test suite produced. Turning off WD helped a lot, but I still got those failures every once in a while. I have since discovered that Microsoft Security Essentials was doing a real time scan, mucking things up. That has to be turned off, too.

This happens, because contrary to UNIX based systems, Windows has real locks. On one side, it is good as the operating system real enforces them. On the other hand it can lead to such scenarios if the applications are not properly coded to work with file locking mechanisms. UNIX systems on the other hand, still have the cooperating locks of the old days, meaning if my application doesn't give a damn about locks, it still can manipulate the file. Which might have some nasty consequences. Does any other operating system makes use of cooperative locks? -- Paulo
