NFS sometimes lock file (I did see a similar problem with Solaris)
Thanks for the tip. I'll code in Windows by default, and add a flag to enable/disable then, since I don't think there's a way to determine if something is coming from NFS.
Although you can lock files over NFS on Unix systems, it should behave no differently than if you were to lock the file on any other filesystem. In other words, unless you explicitly lock the file and check that the file is locked (as locks are only advisory on Unix, they don't stop you from performing any operations if you really want to) you should not have any of the same file locking issues on Unix that you do on Windows. See the the flock and fcntl man pages for more information on Unix file locking.
